50 Therefore will I praise Thee among the nations, Jahve, And I will sing praises nnto Thy name,
51 As He, who giveth great deliverance to His king And sheweth favour to His anointed,
To David and his seed for ever.
Next to a תּפּלּה of David comes a שׁירה (nom. unitatis from שׁיר), which is in many ways both in words and thoughts (Symbolae p. 49) interwoven with the former. It is the longest of all the hymnic Psalms, and bears the inscription: To the Precentor, by the servant of Jahve, by David, who spake unto Jahve the words of this song in the day that Jahve had delivered him out of the hand of all his enemies and out of the hand of Saûl : then he said. The original inscription of the Psalm in the primary collection was probably only לדוד למנצח לעבד ה, like the inscription of Psa 36:1-12. The rest of the inscription resembles the language with which songs of this class are wont to be introduced in their connection in the historical narrative, Exo 15:1; Num 21:17, and more especially Deu 31:30. And the Psalm before us is found again in 2 Sam 22, introduced by words, the manifestly unaccidental agreement of which with the inscription in the Psalter, is explained by its having been incorporated in one of the histories from which the Books of Samuel are extracted, - probably the Annals (Dibre ha-Jamim) of David. From this source the writer of the Books of Samuel has taken the Psalm, together with that introduction; and from this source also springs the historical portion of the inscription in the Psalter, which is connected with the preceding by אשׁר.
David may have styled himself in the inscription עבד ה, just as the apostles call themselves δοῦλοι Ἰησοῦ Χριστοῦ. He also in other instances, in prayer, calls himself “the servant of Jahve,” Psa 19:12, Psa 19:14; Psa 144:10; 2Sa 7:20, as every Israelite might do; but David, who is the first after Moses and Joshua to bear this designation or by-name, could to so in an especial sense. For he, with whom the kingship of promise began, marks an epoch in his service of the work of God no less than did Moses, through whose mediation Israel received the Law, and Joshua, through whose instrumentality they obtained the Land of promise.
