1 Kings 22:27-30

27and say, ‘This is what the king says: Put this fellow in prison and give him nothing but bread and water until I return safely.’ ”

28Micaiah declared, “If you ever return safely, the Lord has not spoken through me.” Then he added, “Mark my words, all you people!”

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

30The king of Israel said to Jehoshaphat, “I will enter the battle in disguise, but you wear your royal robes.” So the king of Israel disguised himself and went into battle.
