2 Chronicles 18:25-29

Then the king of Israel said, Take ye Micaiah, and carry him back to 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 return in peace.

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

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 will go to the battle; but put thou on thy robes. So the king of Israel disguised himself; and they went to the battle.
