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, and they were sitting 1at the threshing floor at the entrance of the gate of Samaria; and all the prophets were prophesying before them. 10Zedekiah the son of Chenaanah made horns of iron for himself and said, “Thus says the Lord, ‘With these you shall gore the Arameans until they are consumed.’” 11All the prophets were prophesying thus, saying, “Go up to Ramoth-gilead and succeed, for the Lord will give it into the hand of the king.”

12Then the messenger who went to summon Micaiah spoke to him saying, “Behold, the words of the prophets are uniformly favorable to the king. So please let your word be like one of them and speak favorably.”
