1 Kings 22:28-30

King James Version

²⁸ 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.

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

³⁰ 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.
