2 Kings 3:13

And Elisha said unto the king of Israel, taking this opportunity to reprove him and to work a wholesome sorrow for his sins in his heart, What have I to do with thee? What business could they have together, since Jehoram was addicted to idolatry? Get thee to the prophets of thy father and to the prophets of thy mother; for he still permitted the priests of Baal to continue in his land. And the king of Israel, with at least some show of humility, said unto him, Nay; for the Lord hath called these three kings together to deliver them into the hand of Moab. So his appeal for help was based upon the fact that the lives and armies of three kings were at stake.
