2 Kings 3:5-7

New Living Translation

⁵ But after Ahab’s death, the king of Moab rebelled against the king of Israel. ⁶ So King Joram promptly mustered the army of Israel and marched from Samaria. ⁷ On 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.”
