1 Kings 22:27-30

27and say, 'Thus says the king, "Put this fellow in prison and feed him meager rations of bread and water, until I come in peace."'"

28And Micaiah said, "If you return in peace, the Lord has not spoken by me." And he said, "Hear, all you peoples!"

29So the king of Israel and Jehoshaphat the king of Judah went up to Ramoth-gilead.

30And the king of Israel said to Jehoshaphat, "I will disguise myself and go into battle, but you wear your robes." And the king of Israel disguised himself and went into battle.
