2 Chronicles 18:9-12

9And the king of Israel and Jehoshaphat the king of Judah, having put on their robes, sat each on his throne; and they sat in an open place at the entrance of the gate of Samaria; and all the prophets prophesied before them.

10And Zedekiah the son of Chenaanah made for himself horns of iron, and he said, Thus saith Jehovah: With these shalt thou push the Syrians, until thou have exterminated them.

11And all the prophets prophesied so, saying, Go up to Ramoth-Gilead, and prosper; for Jehovah will give it into the king's hand.

12And the messenger that went to call Micah spoke to him saying, Behold, the words of the prophets [declare] good to the king with one assent: let thy word therefore, I pray thee, be like one of theirs, and declare good.
