2 Kings 8:19-21

Revised Standard Version

¹⁹ Yet the Lord would not destroy Judah, for the sake of David his servant, since he promised to give a lamp to him and to his sons for ever.

²⁰ In his days Edom revolted from the rule of Judah, and set up a king of their own. ²¹ Then Joram passed over to Za′ir with all his chariots, and rose by night, and he and his chariot commanders smote the E′domites who had surrounded him; but his army fled home.
