2 Kings 3:7 WEB

⁵  But it happened, when Ahab was dead, that the king of Moab rebelled against the king of Israel.

⁶  King Jehoram went out of Samaria at that time, and mustered all Israel.

⁷  He went and sent to Jehoshaphat the king of Judah, saying, The king of Moab has rebelled against me: will you go with me against Moab to battle? He said, I will go up: I am as you are, my people as your people, my horses as your horses.

⁸  He said, Which way shall we go up? He answered, The way of the wilderness of Edom.

⁹  So the king of Israel went, and the king of Judah, and the king of Edom; and they made a circuit of seven days' journey: and there was no water for the host, nor for the animals that followed them.
