2 Kings 3:4-7

4King Mesha of Moab was a sheep breeder. He used to pay the king of Israel an annual tribute of 100,000 lambs and the wool of 100,000 rams.

5But after Ahab’s death, the king of Moab rebelled against the king of Israel.

6So King Joram promptly mustered the army of Israel and marched from Samaria.

7On the way, he sent this message to King Jehoshaphat of Judah: “The king of Moab has rebelled against me. Will you join me in battle against him?” And Jehoshaphat replied, “Why, of course! You and I are as one. My troops are your troops, and my horses are your horses.”
