Matthew Poole and continuators on Psalms 50:14

14. Offer unto God thanksgiving , and pay thy vows unto the most High.

If thou wouldest know what Sacrifices I most prize, and indespensably require, in the first place, it is that of Thankfulness and Praise proportionable to my great and Glorious and numberless Favours, which doth not Consist barely in Verbal acknowledgments, but proceeds from an Heart truly and deeply affected with Gods mercies, and is accompanied with such a Course of Life, as is grateful or Well-pleasing to God: all which is plainly comprehended in Thanksgiving, as that Duty is explained in other Scripture.

Either, 1. Ceremonial vows, the Sacrifices which thou hast vowed to God. Or rather, 2. Moral Vows: for the things here mentioned, are directly opposed unto Sacrifices, and preferred before them: for having disparaged, and in some sort rejected their Sacrifices and Burnt-Offerings, v. 8. it is not likely that he should have a better Opinion of, or value for their vowed Sacrifices; which were of an inferiour sort. He seems therefore to understand those substantial Vows and Promises, and Covenants, which were the very Soul of their Sacrifices, and to which their Sacrifices were but Appurtenances and Seals, as was noted above, on v. 5. whereby they did avouch the Lord to be their God, and to walk in his ways, &c. as it is expressed, Deut. 26. 17. and engaged themselves to Love, and serve and obey the Lord according to that solemn Vow and Covenant, which they entred into at Sinai, Exod. 24. 3. 7, 8. which they oft renewed, and indeed did implicitly repeat in all their Sacrifices, which were appointed for this very end to Confirm this Covenant.
