Great deliverance giveth he to his king
Not that is king over him; for he is King of kings and Lord of lords; but that is made king by him, as David was; who did not usurp the throne, but was anointed king by the appointment of God, and was placed by him upon the throne; to whom he gave great deliverance from his enemies, or "magnified salvations" to him; which were great in kind, and many in number; and as Christ is, whom God has set as his King on his holy hill of Sion, against whom the Heathen raged, and kings and princes set themselves; but he is delivered from them all, and saved from the power of death and the grave, and ever lives to reign over, protect, and defend his people; in ( 2 Samuel 22:51 ) , it is, he is "the tower of salvation for his king", with which compare ( Proverbs 18:10 ) ;
and showeth mercy to his anointed, to David, and to his seed for
evermore;
which may be understood either of David literally, who was the Lord's anointed, and to whom God showed mercy in various instances; and then by his seed is meant the Messiah, who was of his seed according to the flesh; or of the Messiah, whose name signifies Anointed; and who is often called David, ( Ezekiel 34:23 Ezekiel 34:24 ) ( Ezekiel 37:24 Ezekiel 37:25 ) ( Hosea 3:5 ) ; and so some of the Jewish doctors F21 from this verse prove that the name of the Messiah is David: and by his seed are meant his spiritual seed; all the elect of God, who are given him as his children, to whom he stands in the relation of the everlasting Father: and as mercy is kept with him for evermore, ( Psalms 89:28 ) ; so it is shown to them in regeneration, in the forgiveness of their sins, and in their everlasting salvation.
