I will offer to thee the sacrifice of thanksgiving - I will publicly thank and praise thee. See the notes at Psalm 107:22.

And will call upon the name of the Lord - Will worship and praise the Lord.

I will offer to thee - As it is most probable that this Psalm celebrates the deliverance from Babylon, it is no wonder that we find the psalmist so intent on performing the rites of his religion in the temple at Jerusalem, which had been burnt with fire, and was now reviving out of its ruins, the temple service having been wholly interrupted for nearly four-score years.

I will offer to thee the sacrifice of thanksgiving,.... For deliverance from afflictions and death; for loosing his bonds, in every sense; for all mercies, temporal and spiritual; see Romans 6:17; Such sacrifices are according to the will of God; are well pleasing to him, when offered up through Christ, and in faith, and are a glorifying of him. These are more acceptable than all ceremonial sacrifices; and therefore the psalmist determined to offer this, and not them;

and will call upon the name of the Lord; See Gill on Psalm 116:13.

I will offer to thee the sacrifice of thanksgiving, and will call upon the name of the LORD.

17-19. An ampler declaration of his purpose, designating the place, the Lord's house, or earthly residence in Jerusalem.

116:10-19 When troubled, we do best to hold our peace, for we are apt to speak unadvisedly. Yet there may be true faith where there are workings of unbelief; but then faith will prevail; and being humbled for our distrust of God's word, we shall experience his faithfulness to it. What can the pardoned sinner, or what can those who have been delivered from trouble or distress, render to the Lord for his benefits? We cannot in any way profit him. Our best is unworthy of his acceptance; yet we ought to devote ourselves and all we have to his service. I will take the cup of salvation; I will offer the drink-offerings appointed by the law, in token of thankfulness to God, and rejoice in God's goodness to me. I will receive the cup of affliction; that cup, that bitter cup, which is sanctified to the saints, so that to them it is a cup of salvation; it is a means of spiritual health. The cup of consolation; I will receive the benefits God bestows upon me, as from his hand, and taste his love in them, as the portion not only of mine inheritance in the other world, but of my cup in this. Let others serve what masters they will, truly I am thy servant. Two ways men came to be servants. By birth. Lord, I was born in thy house; I am the son of thine handmaid, and therefore thine. It is a great mercy to be children of godly parents. By redemption. Lord, thou hast loosed my bonds, thou hast discharged me from them, therefore I am thy servant. The bonds thou hast loosed shall tie me faster unto thee. Doing good is sacrifice, with which God is well pleased; and this must accompany giving thanks to his name. Why should we offer that to the Lord which cost us nothing? The psalmist will pay his vows now; he will not delay the payment: publicly, not to make a boast, but to show he is not ashamed of God's service, and to invite others to join him. Such are true saints of God, in whose lives and deaths he will be glorified.
