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.

I will pay my vows - I will perform or execute. The word vows here refers probably to the solemn promise which he had made in his sickness - the promise to devote himself to God, should he be restored to health. Compare the notes at Isaiah 38:15, notes at Isaiah 38:20. Such promises are commonly made in sickness, and, alas! almost as commonly disregarded and forgotten on a restoration to health. Yet such vows should be sacredly observed, for
(a) They are right and proper;
(b) they are made in most solemn circumstances;
(c) they are usually sincere;
(d) they are of the nature of a covenant with God;
(e) they are made when we are in the best position to take just views of life - of this life, and of the life to come;
(f) the subsequent life would be happier and better if they were faithfully carried out.
Compare Psalm 22:25, note; Psalm 66:13-14, notes.
In the presence of all his people - Publicly. The vows were made in private; on the sick bed; when alone; in the silence of the night-watches; when no eye was upon him who made them but the eye of God. There is a propriety, however, that the expression of thanksgiving should be public. Compare Isaiah 38:20. Indeed, nothing is more proper than public thanks for a restoration from sickness; and as in our public assemblies prayer is often specially offered for the sick at their own request, so it would be equally proper that, at their request, public thanks should be rendered for their recovery.

I will pay my vows unto the Lord now in the presence of all his people - He was probably now bringing his offering to the temple. These words are repeated, Psalm 116:18.

I will pay my vows unto the Lord now, in the presence of all his people. Make good the resolutions and determinations he made in the strength of divine grace, in the time of his troubles; that should the Lord deliver him out of them, he would give him all the glory, and offer thanksgiving and praise to him; and now being delivered, this he declares he would do, in a public way, before all the people of God, assembled in the house of the Lord, as witnesses of it; see Psalm 66:13.

now--(compare Psalm 115:2). "Oh, that (I may do it)" in the presence, &c.
