1 Kings 15:4

Nevertheless, for David's sake did the Lord his God give him a
lamp in Jerusalem
A kingdom there, as the Targum, splendid and glorious, to be continued in his posterity: to set up his son after him; in it:

and to establish Jerusalem:
to continue that in which the temple was, for the sake of which, and the worship of God in it, there was a succession of David's posterity on the throne of Judah.
