And let thy name be magnified for ever
David desired the performance of the above things not so much for his own sake, and for the sake of his family, as for the glory of God; his great concern was, that God might be magnified, and his greatness displayed, in making him and his family great; and particularly that he might be magnified and glorified in that famous Son of his, the Messiah, as he has been, ( John 13:31 John 13:32 ) ; and by all his people in succeeding ages:
saying, the Lord of hosts [is] the God over Israel;
the Lord of armies above and below, is God over all, and in a special and peculiar manner God over Israel, literal and spiritual, that takes care of them, supplies, protects, and defends them:
and let the house of thy servant David be established before thee;
as he had promised, ( 2 Samuel 7:16 ) .
