1 Kings 22:27-30

27and say, ‘This is what the king says: Put this guy in prison and feed him only a little bread and water until I come back safely.’”

28But Micaiah said, “If you ever return safely, the Lord has not spoken through me.” Then he said, “Listen, all you people!”

29Then the king of Israel and Judah’s King Jehoshaphat went up to Ramoth-gilead.

30But the king of Israel said to Jehoshaphat, “I will disguise myself and go into battle, but you wear your royal attire.” So the king of Israel disguised himself and went into battle.
