2 Kings 8:19
Yet the LORD would not destroy Judah for David his servant’s sake, as he promised him to give him alway a light, and to his children. Yet the LORD would not destroy Judah for David his servant’s sake, as he promised him to give him alway a light, and to his children.
The Lord refused to destroy Judah out of regard for David his servant. He spared the kingdom in order to keep His promise to David to preserve a lamp for him continually and for his children after him. By that forbearance He maintained an enduring line of descendants for David.
