Kings III 22:25-31

²⁵And Micaiah said, Behold, thou shalt see in that day, when thou shalt go into an innermost chamber to hide thyself there.

²⁶And the king of Israel said, Take Micaiah, and convey him away to Shemer the keeper of the city;

²⁷and tell Joash the king’s son to put this fellow in prison, and to feed him with bread of affliction and water of affliction until I return in peace.

²⁸And Micaiah said, If thou return at all in peace, the Lord has not spoken by me.

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

³⁰And the king of Israel said to Jehoshaphat king of Judah, I will disguise myself, and enter into the battle, and do thou put on my raiment. So the king of Israel disguised himself, and went into the battle.

³¹And the king of Syria had charged the thirty-two captains of his chariots, saying, Fight not against small or great, but against the king of Israel only.
