1 Kings 22:3-4

3The king of Israel had said to his servants, “Don’t you know that Ramoth-gilead is ours, but we’re doing nothing to take it from the king of Aram?”

4So he asked Jehoshaphat, “Will you go with me to fight Ramoth-gilead?” Jehoshaphat replied to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”
