2 Kings 3:7 DBY

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

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

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

⁸  And he said, Which way shall we go up? And he said, By way of the wilderness of Edom.

⁹  And 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 army, and for the cattle that followed them.
