2 Chronicles 18:9-12

9Dressed in royal attire, the king of Israel and Jehoshaphat king of Judah were sitting on their thrones at the threshing floor by the entrance of the gate of Samaria, with all the prophets prophesying before them.

10Now Zedekiah son of Chenaanah had made for himself iron horns and declared, “This is what the LORD says: ‘With these you shall gore the Arameans until they are finished off.’”

11And all the prophets were prophesying the same, saying, “Go up to Ramoth-gilead and triumph, for the LORD will deliver it into the hand of the king.”

12Then the messenger who had gone to call Micaiah instructed him, “Behold, with one accord the words of the prophets are favorable to the king. So please let your words be like theirs, and speak favorably.”
