1 Kings 22:8-12

And the king of Israel said unto Jehoshaphat, There is yet one man, Micaiah the son of Imlah, by whom we may enquire of the LORD: but I hate him; for he doth not prophesy good concerning me, but evil. And Jehoshaphat said, Let not the king say so.

Then the king of Israel called an officer, and said, Hasten hither Micaiah the son of Imlah.

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

And Zedekiah the son of Chenaanah made him horns of iron: and he said, Thus saith the LORD, With these shalt thou push the Syrians, until thou have consumed them.

And all the prophets prophesied so, saying, Go up to Ramoth-gilead, and prosper: for the LORD shall deliver it into the king’s hand.
