1 Kings 22:26-30

And the king of Israel said, Take Micaiah, and carry him back unto Amon the governor of the city, and to Joash the king’s son;

And say, Thus saith the king, Put this fellow in the prison, and feed him with bread of affliction and with water of affliction, until I come in peace.

And Micaiah said, If thou return at all in peace, the LORD hath not spoken by me. And he said, Hearken, O people, every one of you.

So the king of Israel and Jehoshaphat the king of Judah went up to Ramoth-gilead.

And the king of Israel said unto Jehoshaphat, I will disguise myself, and enter into the battle; but put thou on thy robes. And the king of Israel disguised himself, and went into the battle.
