Psalms 18:49

“Paul (Rom 15:9) quotes from this doxology to show that under the Old Testament economy, others than the Jews were regarded as subjects of that spiritual government of which David was head, and in which character his deliverances and victories were typical of the more illustrious triumphs of David's greater Son. The language of Psa 18:50 justifies this view in its distinct allusion to the great promise (compare Sa2 7:12). In all David's successes he saw the pledges of a fulfilment of that promise, and he mourned in all his adversities, not only in view of his personal suffering, but because he saw in them evidences of danger to the great interests which were committed to his keeping. It is in…”

“Therefore will I give thanks unto thee - Margin, confess. The Hebrew word - ידה yâdâh - in the form used here, means properly to profess, to confess, to acknowledge; then especially to acknowledge or recognize blessings and favors; in other words, to give thanks, to praise. The idea here is that he would make a public acknowledgment of those blessings which he had received; or that he would cause the remembrance of them to be celebrated among the nations. Among the heathen - Among the nations. See the note at Psalms 18:43. The meaning here is, that he would cause these blessings to be remembered by making a record of them in this song of praise; a song that would be used not only in his…”

“Heathen - David is here transported beyond himself, and speaks this in special relation to Christ who was to be his seed, and of whom he was an eminent type, and by whom alone this was done. And therefore this is justly applied to him, and to his calling of the Gentiles, Rom 15:9. Psalms 18:50”

“18:49 The psalmist’s vision of praise . . . among the nations motivated Paul in his mission to the Gentiles (Rom 15:9).”

“will I give thanks: or, confess, Psa 14:7, Psa 30:12, Psa 72:18, Psa 72:19, Psa 138:4; Sa2 22:50, Sa2 22:51; Rom 15:9; Ti1 6:13 sing: Psa 108:3; Mat 26:30; Rom 15:9 Psalms 18:50”

“(Heb.: 18:50-51) The praise of so blessed a God, who acts towards David as He has promised him, shall not be confined within the narrow limits of Israel. When God's anointed makes war with the sword upon the heathen, it is, in the end, the blessing of the knowledge of Jahve for which he opens up the way, and the salvation of Jahve, which he thus mediatorially helps on. Paul has a perfect right to quote Psa 18:50 of this Psalm ( Rom 15:9), together with Deu 32:43 and Psa 117:1, as proof that salvation belongs to the Gentiles also, according to the divine purpose of mercy. What is said in Psa 18:50 as the reason and matter of the praise that shall go forth beyond Israel, is an echo of the…”
