2 Chronicles 18:9-12

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

10And Zedekiah the son of Chenaanah made for himself horns of iron and said, "Thus says the Lord, 'With these you shall push the Syrians until they are destroyed.'"

11And all the prophets prophesied so and said, "Go up to Ramoth-gilead and triumph. The Lord will give it into the hand of the king."

12And the messenger who went to summon Micaiah said to him, "Behold, the words of the prophets with one accord are favorable to the king. Let your word be like the word of one of them, and speak favorably."
