Psalmen 18:49

(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 Messianic promises in Sa2 7:12-16 which is perfectly reconcileable with the Davidic authorship of the Psalm, as Hitzig acknowledges. And Theodoret does not wrongly appeal to the closing words עד־עולם against the Jews. In whom, but in Christ, the son of David, has the fallen throne of David any lasting continuance, and in whom, but in Christ, has all that has been promised to the seed of David eternal truth and reality? The praise of Jahve, the God of David, His anointed, is, according to its ultimate import, a praising of the Father of Jesus Christ.

This psalm we met with before, in the history of David's life, 2 Sa. 22. That was the first edition of it; here we have it revived, altered a little, and fitted for the service of the church. It is David's thanksgiving for the many deliverances God had wrought for him; these he desired always to preserve fresh in his own memory and to diffuse and entail the knowledge of them. It is an admirable composition. The poetry is very fine, the images are bold, the expressions lofty, and every word is proper and significant; but the piety far exceeds the poetry. Holy faith, and love, and joy, and praise, and hope, are here lively, active, and upon the wing. I. He triumphs in God (Psa 18:1-3). II. He magnifies the deliverances God had wrought for him (v. 4-19). III. He takes the comfort of his integrity, which God had thereby cleared up (Psa 18:20-28). IV. He gives to God the glory of all his achievements (Psa 18:29-42). V. He encourages himself with the expectation of what God would further do for him and his (Psa 18:43-50). To the chief musician, A psalm of David, the servant of the Lord, who spake unto the Lord the words of this song in the day that the Lord delivered him from the hand of all his enemies.

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