1 Kings 22:26-30

Then the king of Israel said, “Take Micaiah and return him to Amon the governor of the city, and to Joash the king’s son;

and say, ‘This is what the king says: “Put this man in prison, and feed him enough bread and water to survive until I return safely.” ’ ”

But Micaiah said, “If you actually return safely, the Lord has not spoken by me.” And he said, “Listen, all you people!” Defeat and Death of Ahab

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

And the king of Israel said to Jehoshaphat, “I will disguise myself and go into the battle, but you put on your robes.” So the king of Israel disguised himself and went into the battle.
