John Gill Bible Commentary

Therefore will I give thanks unto thee, O Lord, among the Heathen,.... These words are cited by the apostle, in Rom 15:9; and applied to the conversion of the Gentiles, which is manifestly prophesied of in some preceding verses of this psalm: there it is rendered, "I will confess to thee among the Gentiles"; and designs not confession of sin, nor profession of the truth, but an acknowledgment of unworthiness, joined with thankfulness for mercies received; done in the most public manner, not only in the congregation of the righteous, but before the Heathen conquered by him; owning before them all, that the victories he had obtained over them were not to be ascribed to his arm and sword, but to the power of the Lord; and sing praises unto thy name; which is comely for the saints to do, and which Jesus Christ himself did, in the great congregation of his disciples, and among the Gentiles, by his apostles, and others, on the account of the conversion of them.
