Now know I that the Lord saveth his Anointed
Not David, though he was the anointed of the God of Jacob, and was anointed with material oil to be king of Israel by Samuel, at the express order of God himself; but David is not here speaking of himself, nor the church of him, but of the Messiah; anointed by Jehovah king over his holy hill of Zion, with the oil of gladness, or the Holy Spirit. The church in prayer rises in her faith, and is strongly assured of the salvation of the Messiah; that though his troubles would be many and great, he should be delivered out of them all; should be heard and helped in the day of salvation, and be freed from the sorrows of death and hell, he should be encompassed with; that he should be raised from the dead; have all power in heaven and earth given him; ascend on high, and triumph over all his enemies; and all his people, all the members of his body, should be saved through him, which is in a sense the salvation of himself;
he will hear him from his holy heaven;
where his throne and temple are, which is the habitation of his holiness, whither the prayers of the Messiah when on earth ascended, where they were received, heard, and answered. Before the church prays that he might be heard, now she believes he would; and that,
with the saving strength of his right hand;
that is, by the exertion of his mighty power, in strengthening him as man to bear up under his sorrows, go through his work, and finish it; by upholding him with his right hand while engaged in it, and by raising him up from the dead with it, and setting him down at it in the highest heavens.
