Jamieson, Fausset and Brown on 2 Kings 3:13-14

13-14. What have I to do with thee? &c.--Wishing to produce a deep spirit of humility and contrition, Elisha gave a stern repulse to the king of Israel, accompanied by a sarcastic sneer, in bidding him go and consult Baal and his soothsayers. But the distressed condition, especially the imploring language, of the royal suppliants, who acknowledged the hand of the Lord in this distress, drew from the prophet the solemn assurance, that solely out of respect to Jehoshaphat, the Lord's true servant, did he take any interest in Jehoram.
