1 Kings 22:3-5

3The king of Israel had said to his officials, “Don’t you know that Ramoth Gilead belongs to us and yet we are doing nothing to retake it from the king of Aram?”

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

5But Jehoshaphat also said to the king of Israel, “First seek the counsel of the Lord.”
