1 Kings 22:27-30

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

28Micaiah then said, “If you ever return safely, then Adonai has not spoken through me.” And he added, “Did you hear, all you people?”

29So the king of Israel and Jehoshaphat the king of Judah marched to Ramot-gilead.

30Then the king of Israel said to Jehoshaphat, “I will disguise myself and go into the battle, but you, put on your robes.” So the king of Israel disguised himself and went into the battle.
