2 Kings 3:4-7

4Now Mesha king of Moab raised sheep, and he had to pay the king of Israel a tribute of a hundred thousand lambs and the wool of a hundred thousand rams.

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

6So at that time King Joram set out from Samaria and mobilized all Israel.

7He also sent this message to Jehoshaphat king of Judah: “The king of Moab has rebelled against me. Will you go with me to fight against Moab?” “I will go with you,” he replied. “I am as you are, my people as your people, my horses as your horses.”
