2 Kings 3:7 ASV

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

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

⁷  And he went and sent to Jehoshaphat the king of Judah, saying, The king of Moab hath rebelled against me: wilt thou go with me against Moab to battle? And he said, I will go up: I am as thou art, my people as thy people, my horses as thy horses.

⁸  And he said, Which way shall we go up? And 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 beasts that followed them.
