13. The cup of salvation He refers to a custom which was prevalent under the Law. For when they rendered solemn thanks to God, a feast was also appointed, at which, in token of their gladness, there was an holy libation. This being a symbol of their deliverance from Egyptian thraldom, is for that reason here called the cup of salvation ³⁸²³⁸²     That there is here an allusion to the cup of wine drunk in the offering of eucharistical sacrifices is very generally admitted by commentators. During the feast that followed these sacrifices, the master of the family took a cup of wine into his hands, and after solemnly giving thanks to God for the mercies experienced, first drank of it himself, and then delivered it to all present to be partaken of in rotation. “The cup here spoken of by the Psalmist,” says Cresswell, “was probably used by the master of a Hebrew family at an entertainment in his own house, at which the remainder of the victims was eaten, after he had offered (Leviticus 7:11, etc.) the sacrifice of a peace-offering for a thanksgiving; when, lifting up the cup of wine in his hand, he called upon the name of the Lord, giving him thanks. The modern Jews are said to use a similar ceremony every year in commemoration of the deliverance of their ancestors from the bondage of Egypt.” Some, indeed, deny that there is any allusion to such eucharistical sacrifices, as Hengstenberg, who observes, that this communion cup is a mere fiction. In the institution of the festival offerings, nothing is indeed said of the cup; but we know from Matthew 26:29, 30, that in the feast of the Passover, for instance, the drinking of a cup of wine and the singing of a hymn were parts of the observance. From Jewish tradition we also learn that such was the ancient practice. See Lightfoot’s Horae Hebraicae on Matthew 26. Our Lord, apparently in imitation of the Jewish custom, as the head of the family, at the feast of the Passover, “took the cup, and gave thanks,” (Luke 22:17.) In allusion to this custom, Paul calls the communion cup in the Lord’s Supper “the cup of blessing,” (1 Corinthians 10:16.) The Psalmist, then, here intimates his intention of publicly yielding thanks to God for the mercies bestowed upon him.
   There was a libation of wine enjoined by the Mosaic law to be made in the temple every morning and evening for a drink-offering, (Numbers 28:7,) to which some suppose there is here a reference, observing, that the three last verses seem to intimate, that the Psalmist was now at the temple, offering the meat-offering, drink-offering, and sacrifices, to the Lord. The term to call upon, signifies to celebrate the name of God; and this he expresses more plainly, subsequently, by saying that he would pay his vows in the assembly of the faithful, the sanctuary alone being the place where sacrifices could be offered. The amount is, that the faithful need not be greatly perplexed about the way of performing their duties, God not demanding from them a return which he knows they are unable to give, but being satisfied with a bare and simple acknowledgment. The proper return is to own our obligation to him for every thing. If God deal so kindly and mercifully with us, and we fail in giving to him the tribute of praise for our deliverance which he claims, then our supineness becomes the more base. And certainly they are unworthy of the enjoyment, I say not of the riches of the world, but of the light of the sun and the air by which we breathe and live, who would rob the Author of them of the small return which so legitimately belongs to him. The Mosaic ritual has indeed been abrogated, and along with it the external libation referred to by David, yet the spiritual service, as we found in Psalm 50:23, “The sacrifice of praise shall glorify me,” is still in force. Let us, however, bear in mind, that God is lawfully praised by us, when we offer in sacrifice not only our tongues, but also ourselves, and all that we possess. And this not because God derives any profit from it, but because it is reasonable that our gratitude should manifest itself in this way.

14 I will pay my vows unto Jehovah The steadfastness of his piety shines forth in this, that, in the midst of his dangers, he had vowed unto God. And now he proves that he by no means forgot these engagements, as most men do, who, when the hand of God lies heavy upon them, implore his help for a short time, but soon bury in oblivion the deliverance which they have received. The Holy Spirit, speaking of the true worship of God, very properly connects, by an indissoluble bond, these two parts of worship, “Call upon me in the day of trouble;” and, “after thy deliverance glorify me,” Psalm 50:15. If any regard it as an absurdity for the faithful to enter into covenant with God by making vows to him, to procure his approbation, my reply is, that they do not promise the sacrifice of praise, to soothe him by their flatteries, as if he were a mortal like themselves, or to bind him to them by proposing some reward, for David had previously protested that he would not offer any recompense. The design, then, and the use of vows is, first, That the children of God may have their hearts strengthened with the confidence of obtaining whatever they ask; and, secondly, That they may be stimulated the more to offer up their tribute of gratitude to God for his mercies. To aid the children of God in their infirmity, the privilege of vowing may surely be conceded to them, for by this means their most merciful Father condescends to allow them to enter into familiar converse with him, provided they make their vows for the object I have stated. Happen what may, nothing must be attempted without his permission. And hence the Papists appear the more ridiculous, who, under pretext of what is advanced in this place, defend all sorts of vows, however foolish and absurd and rashly made; as if drunkenness were lawful, because God permits us to eat.

15. Precious in the eyes of Jehovah is the death of his meek ones. He goes on now to the general doctrine of God’s providential care for the godly, in that he renders them assistance in time of need; their lives being precious in his sight. With this shield he desires to defend himself from the terrors of death, which often pressed upon him, by which he imagined he would instantly be swallowed up. When we are in danger and God apparently overlooks us, we then consider ourselves to be contemned as poor slaves, and that our life is regarded as a thing of nought. And we are aware that when the wicked perceive that we have no protection, they wax the more bold against us, as if God took no notice either of our life or death. In opposition to their erroneous doctrine, David introduces this sentiment, that God does not hold his servants in so little estimation as to expose them to death casually. ³⁸⁴³⁸⁴     “For their death to be precious is, in effect, no more than that it is, so considered, rated at so high a price by God, as that he will not easily grant it to any one that most desires it of him. Absalom here hostilely pursued David and desired his death, he would have been highly gratified with it, taking it for the greatest boon that could have befallen him: but God would not thus gratify him; nor will he grant this desire easily to the enemies of godly men, especially of those that commit themselves to his keeping, as David here did.” — Hammond. We may indeed for a time be subjected to all the vicissitudes of fortune and of the world; we will nevertheless always have this consolation, that God will, eventually, openly manifest how dear our souls are to him. In these times, when innocent blood is shed, and the wicked contemners of God furiously exalt themselves, as if exulting over a vanquished God, let us hold fast by this doctrine, that the death of the faithful, which is so worthless, nay, even ignominious in the sight of men, is so valuable in God’s sight, that, even after their death, he stretches out his hand towards them, and by dreadful examples demonstrates how he holds in abhorrence the cruelty of those who unjustly persecute the good and simple. If he put their tears in a bottle, how will he permit their blood to perish? Psalm 56:8 At his own time he will accomplish the prediction of Isaiah, “that the earth shall disclose her blood,” Isaiah 26:21. To leave room for the grace of God, let us put on the spirit of meekness, even as the prophet, in designating the faithful meek ones, calls upon them to submit their necks quietly to bear the burden of the cross, that in their patience they may possess their souls, Luke 21:19

16 Come, O Jehovah! because I am thy servant. As, in the former verse, he gloried that in him God had given an example of the paternal regard which he has for the faithful, so here he applies, in an especial manner, to himself the general doctrine, by declaring that his fetters had been broken, in consequence of his being included among the number of God’s servants. He employs the term fetters, as if one, with hands and feet bound, were dragged by the executioner. In assigning, as the reason of his deliverance, that he was God’s servant, he by no means vaunts of his services, but rather refers to God’s unconditional election; for we cannot make ourselves his servants, that being an honor conferred upon us solely by his adoption. Hence David affirms, that he was not God’s servant merely, but the son of his handmaid. “From the womb of my mother, even before I was born, was this honor conferred upon me.” He therefore presents himself as a common example to all who shall dedicate themselves to the service of God, and place themselves under his protection, that they may be under no apprehension for their safety while they have him for their defense.
