1 Kings 22:4

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

And he said unto Jehoshaphat, Wilt thou go with me to battle to Ramoth-gilead? And Jehoshaphat said to the king of Israel, I am as thou art, my people as thy people, my horses as thy horses.
