2 Chronicles 18:9-12

9Now the king of Israel and Jehoshaphat the king of Judah were sitting, each on his throne, dressed 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. 10Then Zedekiah the son of Chenaanah made horns of iron for himself and said, “This is what the Lord says: ‘With these you will gore the Arameans until they are destroyed!’” 11All the prophets were prophesying this as well, saying, “Go up to Ramoth-gilead and be successful, for the Lord will hand it over to the king.”

12Then the messenger who went to summon Micaiah spoke to him saying, “Behold, the words of the prophets are 2unanimously favorable to the king. So please let your word be like one of them, and speak favorably.”
