1 Kings 22:27-30

27and say, ‘Thus says the king, “Put this man in prison, and feed him sparingly with the bread and water until I return safely.” ’ ”

28Micaiah said, “If you indeed return safely, the Lord has not spoken by me.” Then he said, “Listen, all you people.”

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

30The king of Israel said to Jehoshaphat, “I will disguise myself and enter the battle, but you put on your [royal] clothing.” So the king of Israel disguised himself and went into the battle.
