1. The earth is Jehovah's. We will find in many other places the children of Abraham compared with all the rest of mankind, that the free goodness of God, in selecting them from all other nations, and in embracing them with his favor, may shine forth the more conspicuously. The object of the beginning of the psalm is to show that the Jews had nothing of themselves which could entitle them to approach nearer or more familiarly to God than the Gentiles. As God by his providence preserves the world, the power of his government is alike extended to all, so that he ought to be worshipped by all, even as he also shows to all men, without exception, the fatherly care he has about them. But since he preferred the Jews to all other nations, it was indispensably necessary that there should be some sacred bond of connection between him and them, which might distinguish them from the heathen nations. By this argument David invites and exhorts them to holiness. He tells them that it was reasonable that those whom God had adopted as his children, should bear certain marks peculiar to themselves, and not be altogether like strangers. Not that he incites them to endeavor to prejudice God against others, in order to gain his exclusive favor; but he teaches them, from the end or design of their election, that they shall then have secured to them the firm and peaceful possession of the honor which God had conferred upon them above other nations, when they devote themselves to an upright and holy life. ² In vain would they have been collected together into a distinct body, as the peculiar people of God, if they did not apply themselves to the cultivation of holiness. In short, the Psalmist pronounces God to be the King of the whole world, to let all men know that, even by the law of nature, they are bound to serve him. And by declaring that he made a covenant of salvation with a small portion of mankind, and by the erection of the tabernacle, gave the children of Abraham the symbol of his presence, thereby to assure them of his dwelling in the midst of them, he teaches them that they must endeavor to have purity of heart and of hands, if they would be accounted the members of his sacred family.

With respect to the word fullness, I admit that under it all the riches with which the earth is adorned are comprehended, as is proved by the authority of Paul; but I have no doubt that the Psalmist intends by the expression men themselves, who are the most illustrious ornament and glory of the earth. If they should fail, the earth would exhibit a scene of desolation and solitude, not less hideous than if God should despoil it of all its other riches. To what purpose are there produced so many kinds of fruit, and in so great abundance, and why are there so many pleasant and delightful countries, if it is not for the use and comfort of men? ³ Accordingly, David explains, in the following clause, that it is principally of men that he speaks. It is his usual manner to repeat the same thing twice, and here the fullness of the earth, and the inhabitants of the world, have the same meaning. I do not, however, deny that the riches with which the earth abounds for the use of men, are comprehended under these expressions. Paul, therefore, (1 Corinthians 10:26) when discoursing concerning meats, justly quotes this passage in support of his argument, maintaining that no kind of food is unclean, because, "the earth is the Lord's, and the fullness thereof."

2. For he hath founded it upon the seas. The Psalmist here confirms the truth, that men are rightfully under the authority and power of God, so that in all places and countries they ought to acknowledge him as King. And he confirms it from the very order manifested in the creation; for the wonderful providence of God is clearly reflected in the whole face of the earth. In order to prove this, he brings forward the proof of it, which is most evident. How is it that the earth appears above the water, but because God purposely intended to prepare a habitation for men? Philosophers themselves admit, that as the element of the water is higher than the earth, it is contrary to the nature of the two elements ⁴ for any part of the earth to continue uncovered with the waters, and habitable. Accordingly, Job (Job 28:11, 25) extols, in magnificent terms, that signal miracle by which God restrains the violent and tempestuous ragings of the sea, that it may not overwhelm the earth, which, if not thus restrained, it would immediately do and produce horrible confusion. Nor does Moses forget to mention this in the history of the creation. After having narrated that the waters were spread abroad so as to cover the whole earth, he adds, that by an express command of God they retired into one place, in order to leave empty space for the living creatures which were afterwards to be created, (Genesis 1:9) From that passage we learn that God had a care about men before they existed, inasmuch as he prepared for them a dwelling-place and other conveniences; and that he did not regard them as entire strangers, seeing he provided for their necessities, not less liberally than the father of a family does for his own children. David does not here dispute philosophically concerning the situation of the earth, when he says, that it has been founded upon the seas. He uses popular language, and adapts himself to the capacity of the unlearned. Yet this manner of speaking, which is taken from what may be judged of by the eye, is not without reason. The element of earth, it is true, in so far as it occupies the lowest place in the order of the sphere, is beneath the waters; but the habitable part of the earth is above the water, and how can we account for it, that this separation of the water from the earth remains stable, but because God has put the waters underneath, as it were for a foundation? Now, as from the creation of the world, God extended his fatherly care to all mankind, the prerogative of honor, by which the Jews excelled all other nations, proceeded only from the free and sovereign choice by which God distinguished them.

3. Who shall ascend unto. It being very well known that it was of pure grace that God erected his sanctuary, and chose for himself a dwelling-place among the Jews, David makes only a tacit reference to this subject. ⁵ He insists principally on the other point contained in the verse, that of distinguishing true Israelites from the false and bastards. He takes the argument by which he exhorts the Jews to lead a holy and righteous life from this, that God had separated them from the rest of the world, to be his peculiar inheritance. The rest of mankind, it is true, seeing they were created by him, belong to his empire; but he who occupies a place in the church is more nearly related to him. All those, therefore, whom God receives into his flock he calls to holiness; and he lays them under obligations to follow it by his adoption. Moreover, by these words David indirectly rebukes hypocrites, who scrupled not falsely to take to themselves the holy name of God, as we know that they are usually lifted up with pride, because of the titles which they take without having the excellencies which these titles imply, contenting themselves with bearing only outside distinctions; ⁶ yea, rather he purposely magnifies this singular grace of God, that every man may learn for himself, that he has no right of entrance or access to the sanctuary, unless he sanctify himself in order to serve God in purity. The ungodly and wicked, it is true, were in the habit of resorting to the tabernacle; and, therefore, God, by the Prophet Isaiah, (Isaiah 1:12) reproaches them for coming unworthily into his courts, and wearing the pavement thereof. But David here treats of those who may lawfully enter into God's sanctuary. The house of God being holy, if any rashly, and without a right, rush into it, their corruption and abuse are nothing else but polluting it. As therefore they do not go up thither lawfully, David makes no account of their going up; yea, rather, under these words there is included a severe rebuke, of the conduct of wicked and profane men, in daring to go up into the sanctuary, and to pollute it with their impurity. On this subject I have spoken more fully on the 15th psalm. In the second part of the verse he seems to denote perseverance, as if he had said, Who shall go up into the hill of Sion, to appear and stand in the presence of God? The Hebrew word Mwq, kum, it is true, sometimes signifies to rise up, but it is generally taken for to stand, as we have seen in the first psalm. And although this is a repetition of the same idea, stated in the preceding clause, it is not simply so, but David, by expressing the end for which they ought to go up, illustrates and amplifies the subject; and this repetition and amplification we find him often making use of in other psalms. In short, how much soever the wicked were mingled with the good in the church, in the time of David, he declares how vain a thing it is to make an external profession unless there be, at the same time, truth in the inward man. What he says concerning the tabernacle of the covenant must be applied to the continual government of the church.

4. He who is clean of hands, and pure of heart. Under the purity of the hands and of the heart, and the reverence of God's name, he comprehends all religion, and denotes a well ordered life. True purity, no doubt, has its seat in the heart, but it manifests its fruits in the works of the hands. The Psalmist, therefore, very properly joins to a pure heart the purity of the whole life; for that man acts a ridiculous part who boasts of having a sound heart, if he does not show by his fruits that the root is good. On the other hand, it will not suffice to frame the hands, feet, and eyes, according to the rule of righteousness, unless purity of heart precede outward continence. If any man should think it absurd that the first place is given to the hands, we answer without hesitation, that effects are often named before their causes, not that they precede them in order, but because it is sometimes advantageous to begin with things which are best known. David, then, would have the Jews to bring into the presence of God pure hands, and these along with an unfeigned heart. To lift up, or to take his soul, I have no doubt is here put for to swear. It is, therefore, here required of the servants of God, that when they swear, they do it with reverence and in good conscience, ⁷ and, under one particular, by synecdoche, is denoted the duty of observing fidelity and integrity in all the affairs of life. That mention is here made of oaths, appears from the words which immediately follow, And hath not sworn deceitfully, which are added as explanatory of what goes before. As, however, there is a twofold reading of the Hebrew word for soul, that is to say, as it may be read, my soul, or his soul, on account of the point hirek, some Jewish commentators read, Who hath not lifted up my soul to vanity, ⁸ and understand the word my as spoken of God, an exposition which I reject as harsh and strained. It is a manner of speaking which carries in it great emphasis, for it means, that those who swear offer their souls as pledges to God. Some, however, may perhaps prefer the opinion, that to lift up the soul, is put for to apply it to lying, an interpretation to the adoption of which I have no great objection, for it makes little difference as to the sense. A question may here be raised -- it may be asked, why David does not say so much as one word concerning faith and calling upon God. The reason of this is easily explained. As it seldom happens that a man behaves himself uprightly and innocently towards his brethren, unless he is so endued with the true fear of God as to walk circumspectly before him, David very justly forms his estimate of the piety of men towards God by the character of their conduct towards their fellow-men. For the same reason, Christ (Matthew 23:23) represents judgment, mercy, and faith, as the principal points of the law; and Paul calls "charity" at one time "the end of the law," (1 Timothy 1:5) and at another "the bond of perfection" (Colossians 3:14.)
