For thy servant David's sake
Not for any virtues, or excellencies or merits, of David, literally understood; rather for the sake of the covenant and promises made with him: but for the sake of the antitypical David, the Messiah, the son of David according to the flesh, and the servant of the Lord as Mediator; for whose sake, and in whose name, prayers and supplications are made and presented;
turn not away the face of thine anointed;
not David; rather Solomon, as the Targum expresses it; so Jarchi: but any of the Lord's anointed, every Christian, or believer in Christ, is an anointed one; and has received the unction from the Holy One, the oil of true grace. And the request is, that God would not turn such away from him, and cause them to depart from his throne of grace, ashamed and disappointed; but hear and answer their petitions, for his Son's sake. In ( 2 Chronicles 6:42 ) ; it is added, "remember the mercies of David thy servant"; the kind and good things promised to him, and perform them.
