2 Chronicles 18:9-12

9Now the king of Israel and Jehoshaphat the king of Judah were sitting, each on his throne, arrayed in their robes; they were sitting at the threshing floor at the entrance of the gate of Samaria; and all the prophets were prophesying before them.

10Zedekiah the son of Chenaanah had made horns of iron for himself; and said, “Thus says the Lord: ‘With these you shall gore the Arameans (Syrians) until they are destroyed.’ ”

11All the prophets prophesied this, saying, “Go up to Ramoth-gilead and succeed; the Lord will hand it over to the king.”

12The messenger who went to call Micaiah said to him, “Listen, the words of the prophets are of one accord, foretelling a favorable outcome for the king. So just let your word be like one of them and speak favorably.”
