2 For I have said, Mercy shall be built up for ever. He assigns the reason why he perseveres in singing the Divine praises in the midst of adversities; which is, that he does not despair of the manifestation of God’s loving-kindness towards his people, although at present they were under severe chastisement. Never will a man freely open his mouth to praise God, unless he is fully persuaded that God, even when he is angry with his people, never lays aside his fatherly affection towards them. The words I have said, imply that the truth which the inspired writer propounds was deeply fixed in his heart. ⁵²³⁵²³     “Ex tristi ruinae spectaculo.” — Lat. “Voyant ce commoncement pitoyable d’une ruine.” — Fr. Whatever, as if he had said, has hitherto happened, it has never had the effect of effacing from my heart the undoubted hope of experiencing the Divine favor as to the future, and I will always continue steadfastly to cherish the same feeling. It is to be observed, that it was not without a painful and arduous conflict that he succeeded in embracing by faith the goodness of God, which at that time had entirely vanished out of sight; — this we say is to be particularly noticed, in order that when God at any time withdraws from us all the tokens of his love, we may nevertheless learn to erect in our hearts that everlasting building of mercy, which is here spoken of, — a metaphor, by which is meant that the Divine mercy shall be extended, or shall continue till it reach its end or consummation. In the second clause of the verse something must be supplied. The sense, in short, is, that the Divine promise is no less stable than the settled course of the heavens, which is eternal and exempt from all change. By the word heavens I understand not only the visible skies, but the heavens which are above the whole frame of the world; for the truth of God, in the heavenly glory of his kingdom, is placed above all the elements of the world.

3 I have made a covenant with my chosen. ⁵²⁴⁵²⁴     “The word אמרתי, ‘I have said,’ is used, in the Book of Psalms, to express two things; either a fixed purpose, or a settled opinion of the person speaking. The Psalmist, therefore, delivers the whole of this second verse in his own person, and introduces not God speaking till the next verse.” — Horsley The more effectually to confirm himself and all the godly in the faith of the Divine promise, he introduces God himself as speaking and sanctioning, by his authority, what had been said in the preceding verse. As faith ought to depend on the Divine promise, this manner of speaking, by which God is represented as coming forward and alluring us to himself by his own voice, is more forcible than if the prophet himself had simply stated the fact. And when God in this way anticipates us, we cannot be charged with rashness in coming familiarly to him; even as, on the contrary, without His word we have no ground to presume that he will be gracious to us, or to hope, at the mere suggestion of our own fancy, for what he has not promised. Moreover, the truth of the promise is rendered still more irrefragable, when God declares that he had made a covenant with his servant David, ratified by his own solemn oath. It having been customary in ancient times to engrave leagues and covenants on tables of brass, a metaphor is here used borrowed from this practice. God applies to David two titles of distinction, calling him both his chosen and his servant. Those who would refer the former appellation to Abraham do not sufficiently attend to the style of the Book of Psalms, in which it is quite common for one thing to be repeated twice. David is called the chosen of God, because God of his own good pleasure, and from no other cause, preferred him not only to the posterity of Saul, and many distinguished personages, but even to his own brethren. If, therefore, the cause or origin of this covenant is sought for, we must necessarily fall back upon the Divine election.

The name of servant, which follows immediately after, is not to be understood as implying that David by his services merited any thing at the hand of God. He is called God’s servant in respect of the royal dignity, into which he had not rashly thrust himself, having been invested with the government by God, and having undertaken it in obedience to his lawful call. When, however, we consider what the covenant summarily contains, we conclude that the prophet has not improperly applied it to his own use, and to the use of the whole people; for God did not enter into it with David individually, but had an eye to the whole body of the Church, which would exist from age to age. The sentence, I will establish thy throne for ever, is partly to be understood of Solomon, and the rest of David’s successors; but the prophet well knew that perpetuity or everlasting duration, in the strict and proper sense, could be verified only in Christ. In ordaining one man to be king, God assuredly did not have a respect to one house alone, while he forgot and neglected the people with whom he had before made his covenant in the person of Abraham; but he conferred the sovereign power upon David and his children, that they might rule for the common good of all the rest, until the throne might be truly established by the advent of Christ.

5. And the heavens shall praise thy wondrous work. The prophet, having spoken of God’s covenant, even as faith ought to begin at the word, now descends to a general commendation of his works. It is, however, to be observed, that when he treats of the wonderful power of God, he has no other end in view than to exalt and magnify more highly the holiness of the covenant. He exclaims, that this is the God who has rightful claims to be served and feared, who ought to be believed, and upon whose power the most unhesitating confidence may be reposed. The words wondrous work, in the first clause, I would therefore limit to the power which God displays in preserving and maintaining his Church. The heavens, it is true, are most excellent witnesses and preachers of God’s wonderful power; but from attending to the scope of the passage, it will be still more evident, that the encomiums here pronounced have all a special reference to the end of which I have spoken. Some interpreters judiciously explain the word heavens, of the angels, among whom there is a common joy and congratulation in the salvation of the Church. This interpretation is confirmed from the last clause of the verse, in which it is asserted, that God’s truth will be celebrated in the congregation of the saints There is no doubt, that the same subject is here prosecuted, and that by the word truth, it is intended to signalise the remarkable deliverances by which God had manifested his faithfulness to the promises made to his servants.

6 For who in the clouds can be compared to Jehovah? The prophet now proceeds to illustrate farther what he had said respecting God’s wonders, and exclaims emphatically, Who in the clouds can be compared to God? The reason why he speaks of the clouds, or heaven, is because, what is not surprising, nothing is to be found upon the earth which can at all approach the glory of God. Although man excels other living creatures, yet we see how contemptible and miserable his condition is, or rather, how full it is of shame and reproach. Whence it follows, that under heaven there is no excellence which can compete with that of God. But when we ascend to heaven, immediately ravished with admiration, we conceive of a multitude of gods, which do away with the true God. The last clause of the verse, in which it is said, that among the sons of the gods there is none like the true and only God, is an explanation of the first. The opinion of some, that by the clouds, or the heavens, is to be understood the sun, moon, and stars, is disproved by the context itself. The amount then is, that even in the heavens, God alone has the entire pre-eminence, having there none as a companion or equal. The appellation the sons of the gods is here given to angels, because they neither have their origin from the earth, nor are clothed with a corruptible body, but are celestial spirits, adorned with a Divine glory. It is not meant that they are a part of the Divine essence or substance, as some fanatics dream; but as God displays his power in them, this title is attributed to them, to distinguish between their nature and ours. In short, although a greater majesty shines forth in the angels than in other creatures, at the contemplation of which we are ravished with admiration, yet come they not near God, so as to obscure and impair his glory by their excellence, or to share with him in the sovereignty of the universe. This is a point worthy of our careful attention; for, although God everywhere declares in his word that the angels are only his servants, and always ready to execute his commands, yet the world, not contented with having only one God, forges for itself a countless number of deities.

To the same effect is the following verse, in which it is affirmed, that God is very terrible in the assembly of the saints. In these words is censured that devilish superstition, to which almost all men are prone, of exalting angels beyond measure, and without reason. But if the angels themselves tremble, and are afraid before the Divine Majesty, why should they not be regarded as subjects, and kept in their own rank, that God alone may have the sovereignty entirely to himself? Farther, when they are represented as around God, the meaning is, that they surround his royal throne like body-guards, and are always ready to execute his behests. In the subsequent verse the same thing is repeated yet again, Who is a strong God as thou art? and this is done, that at least the fear of the Divine Majesty may teach us to beware of robbing him of the honor which belongs to him. That we may not, however, by too much fear, be prevented from approaching him, some portion of sweetness is intermingled with this description, when it is declared, that his truth is to be seen round about him on all sides; by which we are to understand, that God is always steadfast in his promises, and that whatever changes may happen, he nevertheless continues invariably true, both before and behind, on the right hand and on the left. ⁵²⁸⁵²⁸     Ainsworth reads, “God is daunting terrible.” The original word is נערף, naarats, from ערף, arats, he was broken, bruised, terrified. “An epithet of God,” says Bythner “as though breaking all things.”

9. Thou governest the pride of the sea. I have already observed that what the prophet has hitherto spoken generally concerning the power of God, is to be referred to the miracle of the deliverance of the Israelites from Egypt, which he now celebrates in express terms. According to the interpretation of some, God is said to still the impetuous waves of the sea, because he does not suffer it to break forth and overflow the whole world by a deluge. But I would read the 9th and 10th verses connectedly, and would understand the prophet as speaking of the Red Sea, which God divided to make a way for the chosen tribes to pass over. The Psalmist adds immediately after, that all the land of Egypt was overthrown as a wounded man By these words he magnifies the grace of God, which was displayed in the deliverance of the Church. He intended, there can be no doubt, to set before his own mind and the minds of others, the paternal love of God, to encourage both himself and others to have recourse to Him for succor, with the greater freedom and alacrity. And in affirming that God had broken in pieces his enemies with his mighty arm, he concludes from the past experience of the Church, that his mode of acting will be always similar, whenever in his infinite wisdom he sees it to be required.

11 The heavens are thine, the earth also is thine. He again repeats, the third time, that the same God who had been the deliverer of the chosen people exercises supreme dominion over the whole world. From the fact that God created all things, he concludes, that it is He who actually presides over, and controls whatever takes place in heaven and in earth. It would be absurd to suppose, that the heavens, having been once created by God, should now revolve by chance, and that things should be thrown into confusion upon the earth either at the will of men, or at random, when it is considered that it belongs to God to maintain and govern whatever he has created; unless, like the heathen, we would imagine that he enjoys himself in beholding all the works of his hand, in this beautiful theater of the heaven and the earth, without giving himself any farther trouble about them. In speaking of the south and the north, and also of the mountains, Tabor and Hermon, the prophet accommodates his language to the unrefined apprehension of the common people: as if he had said, there is no part of the fabric of the world which does not reverence and honor its Creator. I also connect with this the next verse, which affirms, that the arm of God is furnished with power, his hand with strength, and that his right hand is exalted Some resolve the two last clauses of the verse into the form of a prayer, Strengthen thy hand, lift up thy right hand; but this seems too much removed from the mind of the prophet, who, with the simple view of encouraging all the godly, celebrates the inconceivable power of God.

14. Righteousness and judgement are the place of thy throne. These encomiums serve more effectually to confirm the hope of true believers than if the Divine power alone had been presented to our view. Whenever mention is made of God, it behoves us to apply our minds principally to those attributes of his nature which are specially fitted for establishing our faith, that we may not lose ourselves by vainly indulging in subtile speculations, by which foolish men, although they may minister to their own mental recreation, make no advances to the right understanding of what God really is. The prophet, therefore, in allusion to the insignia and pomp of kings, declares that righteousness and judgment are the pillars of the throne on which God sits conspicuous in sovereign state, and that mercy and truth are, as it were, his pursuivants; as if he had said, “The ornaments with which God is invested, instead of being a robe of purple, a diadem, or a scepter, are, that he is the righteous and impartial judge of the world, a merciful father, and a faithful protector of his people.” Earthly kings, from their having nothing in themselves to procure for them authority, and to give them dignity, ⁵³³⁵³³     Tabor is a mountain of Judea, and Hermon (Psalm 133:3) of Syria, the former to the west, and the latter to the east of the Jordan; so that they may be considered as put for the East and the West. Accordingly, the Chaldee paraphrase is, “Thou hast created the desert of the north, and the inhabitants of the south; Tabor on the west, and Hermon on the east, sing praises to thy name.” “These mountains,” says Warner, “were at a considerable distance from each other. This indicates, that the most distant parts of the land shall be equally blessed; have a like cause of rejoicing.” are under the necessity of borrowing elsewhere what will invest them therewith; but God having in himself an all-sufficiency, and standing in no need of any other helps, exhibits to us the splendor of his own image in his righteousness, mercy, and truth.

15. Blessed is the people that know the joyful sound. Here the same train of reflection concerning the Church is pursued, not only because unbelievers are blind to the consideration of God’s works, but also because the prophet has no other purpose in view than to inspire the godly with good hope, that they may with confidence rely upon God, and not be discouraged by any adversities from boldly calling upon him. It is declared that those are happy to whom it is given to rejoice in God; for although all men in common are sustained and nourished by his liberality, yet the feeling of his paternal goodness is far from being experienced by all men in such a manner as to enable them, from a certain persuasion that he is favorable to them, to congratulate themselves upon their happy condition. It is, therefore, a singular privilege which he confers upon his chosen ones, to make them taste of his goodness, that thereby they may be encouraged to be glad and rejoice. And, in fact, there is not a more miserable condition than that of unbelievers, when by their brutish insensibility they trample under foot the Divine benefits which they greedily devour; for the more abundantly God pampers them, the fouler is their ingratitude. True happiness then consists in our apprehending the Divine goodness which, filling our hearts with joy, may stir us up to praise and thanksgiving.

The prophet afterwards proves from the effect, that those who with joy and delight acknowledge God to be their father are blessed, because they not only enjoy his benefits, but also, confiding in his favor, pass the whole course of their life in mental peace and tranquillity. This is the import of walking in the light of God’s countenance: it is to repose upon his providence from the certain persuasion that he has a special care about our well-being, and keeps watch and ward effectually to secure it. The expressions rejoicing in his name, and glorying in his righteousness, are to the same purpose. The idea involved in them is, that believers find in God abundant, yea more than abundant, ground to rejoice and glory. The word daily appears to denote steadfast and unwavering perseverance; and thus there is indirectly censured the foolish arrogance of those who, inflated only with wind and presuming on their own strength, lift up their horns on high. Standing as they do upon an insecure foundation, they must at length inevitably fall. Whence it follows, that there is no true magnanimity nor any power which can stand but that which leans upon the grace of God alone; even as we see how Paul (Romans 8:31) nobly boasts, “If God be for us, who can be against us?” and defies all calamities both present and to come.

17. For thou art the glory of their strength. The same sentiment is confirmed when it is declared, that God never leaves his faithful servants destitute of strength. By the appellation the glory of their strength, which is ascribed to him, is meant that they are always so sustained by his present aid as to have just ground to glory in him; or which amounts to the same thing, that his power appears always glorious in aiding and sustaining them. They are, however, at the same time, reminded of the duty of yielding to God all the praise of their being preserved in safety. If this is true as to the present life, it is much more truly applicable to the spiritual life of the soul. Farther, the more highly to magnify this instance of God’s liberality, we are taught, at the same time, that it depends entirely upon his good pleasure, there being no other cause of it. ⁵³⁶⁵³⁶     “The Hebrew ליהוה, must be rendered of or from the Lord, in both places in this verse: ‘Of the Lord is our shield or defense;’ ‘Of the Lord, or from him,’ i e., of his appointment, ‘is our King.’”— Hammond Whence it follows, that they are wholly bound and indebted to Him who is induced by his free bounty alone to continue to extend to them his help.

18. For to Jehovah is our buckler. As the chief protection of the people was in the person of their king, it is here expressly shown, that the maintenance of the welfare of the faithful by his instrumentality is the gift of God. But it is to be noticed, that the prophet’s mind was not so fixed upon this temporal and transitory kingdom as to neglect, at the same time, to consider the end of it, as we shall presently see. He knew that it was only on account of Christ that God made his favor to flow upon the head of the Church, and from thence upon the whole body. And, in the first place, while he calls the king metaphorically a buckler, — a figurative expression frequently employed in Scripture, — he confesses that when the people are defended by his hand and working, it is nevertheless done by the providence of God, and is thus to be traced to a higher source than human agency. The same thing is again repeated in the second clause, in which it is affirmed, that the king was given by God to govern the people; and that, therefore, the defense which comes from the king is a blessing of God. Moreover, we must remember that what is said of this kingdom, which was a shadow of something greater, properly applies to the person of Christ, whom the Father has given to us to be the guardian of our welfare, that we may be maintained and defended by his power.

19. Then thou spakest in vision to thy meek ones. The Psalmist now declares at greater length why he said that the king, set over the chosen people for the preservation of the public good, was given them from heaven; namely, because he was not chosen by the suffrages of men, nor usurped at his own hand the supreme power, nor insinuated himself into it by corrupt arts, but was elected by God to be the instrument of maintaining the public good, and performed the duties of his office under the auspices and conduct of God. The design of the prophet, as we shall shortly see more clearly, is to distinguish this Divinely-appointed king from all other kings. Although what Paul teaches in Romans 13:1, is true, “There is no power but of God;” yet there was a great difference between David and all earthly kings who have acquired sovereign power by worldly means. God had delivered the scepter to his servant David immediately with his own hand, so to speak, and had seated him on the royal throne by his own authority. The particle אז, az, which properly signifies then, is taken also for long since, or in old time. The meaning, therefore, is, that whereas some are born kings, succeeding their fathers by right of inheritance, and some are elevated to the royal dignity by election, while others acquire it for themselves by violence and force of arms, God was the founder of this kingdom, having chosen David to the throne by his own voice. Farther, although he revealed his purpose to Samuel, yet as the plural number is here used, implying, that the same oracle had been delivered to others, we may certainly conclude that it had been communicated to other prophets that they might be able, with one consent, to bear testimony that David was created king by the Divine appointment. And, indeed, as other distinguished and celebrated prophets lived at that time, it is not very probable that a matter of so great importance was concealed from them. But Samuel alone is named in this business, because he was the publisher of the Divine oracle and the minister of the royal anointing. As God in those days spake to his prophets either by dreams or by visions, this last mode of revelation is here mentioned.

There next follows the substance or amount of the Divine oracle, That God had furnished with help the strong or mighty one whom he had chosen to be the supreme head and governor of the kingdom. David is called strong, not because naturally and in himself he excelled in strength, (for, as is well known, he was of small stature, and despised among his brethren, so that even Samuel passed him over with neglects) but because God, after having chosen him, endued him with new strength, and other distinguished qualities suitable for a king; even as in a parallel case, when Christ chose his apostles, he not only honored them with the title, but at the same time bestowed the gifts which were necessary for executing their office. And at the present day he imparts to his ministers the same grace of his Spirit. The strength of David, then, of which mention is here made, was the effect of his election; for God, in creating him king, furnished him at the same time with strength adequate for the preservation of the people. This appears still more distinctly from the second clause, where this invincible strength is traced to its source: I have exalted one chosen from among the people. All the words are emphatic. When God declares that he exalted him, it is to intimate the low and mean condition in which David lived, unknown and obscure, before God stretched out his hand to him. To the same effect is the expression which follows, from among the people. The meaning is, that he was at that time unnoted, and belonged to the lowest class of the people, and gave no indications of superior excellence, being the least esteemed of his father’s children, in whose country cottage he held the humble office of a herdsman. ⁵³⁹⁵³⁹     “L’ennemi n’aura puissance sur luy.” — Fr. “The enemy shall not have power over him.” By the word chosen, God calls us back to the consideration of his own free will, as if he forbade us to seek for any other cause of David’s exaltation than his own good pleasure.

20 I have found David my servant. The prophet confirms the same proposition, That there was nothing of royalty in David, who owed all to the sovereignty of God in preventing him by his grace. Such is the import of the word found, as if God had said, When I took him to elevate him, this proceeded entirely from my free goodness. The name servant, therefore, does not denote any merit, but is to be referred to the divine call. It is as if God had said, that he confirmed and ratified by his authority the sovereign power of David; and if He approved it, its legitimacy is placed beyond all doubt. The second clause of the verse affords an additional confirmation of God’s free election: With my holy oil have I anointed him. This anointing, which was not the fruit of David’s own policy, but which he obtained contrary to all expectation, was the cause of his elevation to the estate of royalty. God then having of himself, and according to his mere good pleasure, anticipated David, that he might anoint him king by the hand of Samuel, he justly declares that he found him. It is afterwards added, that he will be the guardian and protector of this kingdom of which he was the founder; for it is not his usual way to abandon his works after having commenced them, but, on the contrary, to carry them forward by a continued process of improvement to their completion.

22 The enemy shall not exact upon him. ⁵⁴⁰⁵⁴⁰     “Quum ultimus esset in rustico tugurio, et inter pecuarios.” — Lat. “Veu qu’il estoit le plus petit en la maison de son pere, et qu’en ce mesnage de village il estoit de ceux qui gardoyent les bestes.” — Fr. Here it is declared in express terms, that although David may not be without enemies, the power of God will be always ready to maintain and defend him, that he may not be oppressed with unrighteous violence. It is accordingly affirmed, that David will not be tributary to his enemies, as he who is vanquished in battle is constrained to grant such conditions of peace as his conqueror may dictate, however injurious to himself these may be. When his enemies are called sons of iniquity, it is tacitly intimated, that this government will be so exempt from tyranny and extortion, that whoever shall attempt to overthrow it will be involved in the perpetration of wrong and wickedness. The amount is, that David and his successors will be so secure and strongly fortified by the divine protection, that it will be impossible for their enemies to treat them as they would wish. In regard to the fact, that God suffered this kingdom to be greatly afflicted, so that David’s successors were constrained to pay a vast amount of tribute to foreign and heathen kings, it is not at variance with this promise; for, although the power of the kingdom was reduced, it was enough that the root still remained, until Christ came, in whose hand the kingdom was at length firmly established. As both the king and the people wickedly rejected this singular blessing of God, the kingdom was often shaken through their own default, afterwards impaired, and finally ruined. Yet God, to confirm his oracle concerning the perpetuity of this kingdom, ceased not all along to cherish and preserve some hope, by contending against their ingratitude. Besides, when mention is made of David’s haters and oppressors, it is intimated, that this throne will not be privileged with exemption from annoyances and troubles, inasmuch as there will be always some who will rise up in hostility against it, unless God set himself in opposition to them.

24 My truth and my mercy shall be with him. God shows that he will continue to exercise without intermission that grace which he had manifested towards David at first. These words are as if he had said, that to prove himself faithful to his word, he would be always gracious and bountiful. Thus We see that God, not only at the outset, furnished David with testimonies of his goodness, but that he always continued to deal with him in the same merciful way. This has a reference to the whole Church of Christ, so that the divine goodness is manifested in the whole course of our salvation, and not only at our first entrance upon it, as these shufflers and sophists the Sorbonists foolishly talk. ⁵⁴³⁵⁴³     “I will make him my first-born; i.e., as the eldest son of a family ranks the highest, and receives the most from his father, so shall David be first in the order of kings, who, when they are legitimate sovereigns, may be regarded as the sons of God, their common Father: comp. Genesis 27:1, etc.; Exodus 4:22; Deuteronomy 21:17; Psalm 2:7; Colossians 1:15. In Isaiah 14:30, by the first-born of the poor, is meant the extreme of that class, they who are the poorest of the poor.” — Cresswell. The horn of David denotes here, as it often does in other places, his glory, dignity, and power. The meaning therefore is, that by the grace of God, this kingdom shall always flourish and prosper.

25. And I will set his hand in the sea. The vast extent of the kingdom is here adverted to. As the people by their wickedness had, as it were, blocked up the way, and intercepted the blessing of God, their inheritance was more limited than the promise implied. But now God declares, that during the reign of David, it will be again enlarged, so that the people shall possess the whole country, from the sea even to the river Euphrates. From this we gather, that what God had promised by Moses was fulfilled only in the person of David, that is to say, from his time. ⁵⁴⁴⁵⁴⁴     “Sicuti nugantur Sophistae.” — Lat. “Comme gazouillent ces brouillons et Sophistes de Sorbonistes.” — Fr. By the rivers may be understood, either the Euphrates alone, which is cut into many channels, or the other neighboring rivers on the coast of Syria.

26. He shall cry to me, Thou art my Father. In this verse it is declared, that the chief excellence of this king will consist in this, that he will be accounted the Son of God. This indeed is a title of honor, which is applied to all whom God ordains to be kings, as we have seen in a previous psalm,

“I have said, Ye are gods; and all of you are children of the Most High:”
(Psalm 82:6)

but in the passage before us, something special is expressed of the holy king whom God had chosen, and it is intended to say, that he will be the son of God in a different sense. We shall immediately see in the subsequent verse, how he is placed in a higher rank than the kings of the earth, although they may sway the scepter over a larger extent of country. It was therefore a privilege peculiar to only one king in this world, to be called the Son of God. Had it been otherwise, the apostle reasoned not only inconclusively but absurdly, in quoting this text as a proof of the doctrine, that Christ is superior to the angels:

“I will be to him a Father, and he shall be to me a Son,”
(Hebrews 1:5.)

Angels, and kings, and all who are regenerated by the Spirit of adoption, are called sons of God; but David, when God promises to take him for his son, is, by singular prerogative, elevated above all others to whom this designation is applied. This is still more apparent from the following verse, in which he is called God’s first-born, because he is higher than all the kings of the earth; and this is an honor which transcends all the dignity both of men and angels. If it is objected, that David being a mortal man could not be equal to the angels, the obvious answer is, that if he is considered in himself, he cannot justly be elevated to the same rank with them, but with the highest propriety he may, in so far as for a time he represented the person of Christ.

28. And I will keep my mercy to him for ever. We see how God frequently repeats, that he had set up the kingdom of David with the express design of establishing it for ever. By placing his mercy first in order, and then adding his covenant, he points out the cause of this covenant, intimating in one word, that it is gratuitous, and that his grace is not only the foundation on which it rests, but also the cause why it is preserved inviolate. The amount is, that God will be always merciful to David, in order that his covenant may never fail. From this it follows, that its inviolability depends upon the mere good pleasure of God. In the next verse, God expresses the effect of his truth, declaring, that the posterity of David will sit for ever on the royal throne. There being nothing under heaven of long continuance, the days of heaven is an expression employed to denote everlasting duration. Whence it follows, that this prophecy cannot have its full accomplishment in any till we come to Christ, in whom alone, in the strict and proper sense, this everlasting duration is to be found.
