2 Chronicles 18:9-17

9 And the king of Israel and Jehoshaphat king of Judah sat either of them on his throne, clothed in their robes, and they sat in a void place at the entering in of the gate of Samaria; and all the prophets prophesied before them.
10 And Zedekiah the son of Chenaanah had made him horns of iron, and said, Thus saith the LORD, With these thou shalt push Syria until they be consumed.
11 And all the prophets prophesied so, saying, Go up to Ramothgilead, and prosper: for the LORD shall deliver it into the hand of the king.
12 And the messenger that went to call Micaiah spake 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 speak thou good.
13 And Micaiah said, As the LORD liveth, even what my God saith, that will I speak.
14 And when he was come to the king, the king said unto him, Micaiah, shall we go to Ramothgilead to battle, or shall I forbear? And he said, Go ye up, and prosper, and they shall be delivered into your hand.
15 And the king said to him, How many times shall I adjure thee that thou say nothing but the truth to me in the name of the LORD?
16 Then he said, I did see all Israel scattered upon the mountains, as sheep that have no shepherd: and the LORD said, These have no master; let them return therefore every man to his house in peace.
17 And the king of Israel said to Jehoshaphat, Did I not tell thee that he would not prophesy good unto me, but evil?
