2 Chronicles 18:27-29

King James Version

²⁷ And Micaiah said, If thou certainly return in peace, then hath not the Lord spoken by me. And he said, Hearken, all ye people.

²⁸ So the king of Israel and Jehoshaphat the king of Judah went up to Ramothgilead.

²⁹ And the king of Israel said unto Jehoshaphat, I will disguise myself, and I will go to the battle; but put thou on thy robes. So the king of Israel disguised himself; and they went to the battle.
