Matthew Henry on 2 Kings 3:6-19
Jehoram has no sooner got the sceptre into his hand than he takes the sword into his hand, to reduce Moab. Crowns bring great cares and perils to the heads that wear them; no sooner in honour than in war. Now here we have,
I. The concerting of this expedition between Jehoram king of Israel and Jehoshaphat king of Judah. Jehoram levied an army (Kg2 3:6), and such an opinion he had of the godly king of Judah that, 1. He courted him to be his confederate: Wilt thou go with me against Moab? And he gained him. Jehoshaphat said, I will go up. I am as thou art, Kg2 3:7.
