2 Kings 8:19

Yet the Lord would not destroy Judah for David his servant's
sake
Not for his merits, but for the mercy he assured him of:

as he promised him to give to him always a light, [and] to his
children;
or a kingdom, as the Targum; therefore he would not utterly destroy the tribe, nor suffer the sceptre or government to depart from it till the Messiah came, see ( Psalms 132:11 Psalms 132:17 ) .
