1 Kings 22:8-10

8And the king of Israel said to Jehoshaphat, There is yet one man by whom we may inquire of Jehovah; but I hate him, for he prophesies no good concerning me, but evil: [it is] Micah the son of Imlah. And Jehoshaphat said, Let not the king say so.

9Then the king of Israel called a chamberlain, and said, Fetch quickly Micah the son of Imlah.

10And the king of Israel and Jehoshaphat the king of Judah, having put on their robes, sat each on his throne, in the open place at the entrance of the gate of Samaria; and all the prophets prophesied before them.
