1 Kings 22:3-4

3Now the king of Israel said to his servants, “Do you know that Ramoth in Gilead is ours, yet we are still doing nothing to take it from the hand of the king of Aram?”

4And Ahab said to Jehoshaphat, “Will you go with me to battle at Ramoth-gilead?” Jehoshaphat said to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”
