5 But when Ahab died, the king of Moab rebelled against the king of Israel.

6 So King Jeho'ram marched out of Sama'ria at that time and mustered all Israel. 7 And he went and sent word to Jehosh'aphat king of Judah, "The king of Moab has rebelled against me; will you go with me to battle against Moab?" And he said, "I will go; I am as you are, my people as your people, my horses as your horses."

Matthew Henry's Commentary on 2 Kings 3:5-7

Commentary on 2 Kings 3:1-5

(Read 2 Kings 3:1-5)

Jehoram took warning by God's judgment, and put away the image of Baal, yet he maintained the worship of the calves. Those do not truly repent or reform, who only part with the sins they lose by, but continue to love the sins that they think to gain by.

Commentary on 2 Kings 3:6-19

(Read 2 Kings 3:6-19)

The king of Israel laments their distress, and the danger they were in. He called these kings together, yet he charges it upon Providence. Thus the foolishness of man perverteth his way, and then his heart fretteth against the Lord, Psalm 84:6. We need not inquire whence the water came. God is not tied to second causes. They that sincerely seek for the dew of God's grace, shall have it, and by it be made more than conquerors.
