1 Kings 22:27-30

27Say to them, “The king commands you to put this man in prison. Feed him with only a little bread and water until I return safely from the battle.” ’

28Micaiah said, ‘If you do return safely, it will show that I have not spoken the Lord's message.’ Then he said to all the people who were there, ‘Remember what I have said to King Ahab!’

29So King Ahab of Israel and King Jehoshaphat of Judah went to attack Ramoth Gilead.

30King Ahab said to Jehoshaphat, ‘When we go into the battle, I will wear ordinary clothes. People will not recognize me as the king. But you should wear your royal clothes.’ So the king of Israel went into the battle as if he was an ordinary soldier.
