2 Chronicles 18:9-12

9The king of Israel and Jehoshaphat king of Judah, clothed in their robes, sat each on his throne; and they sat at a threshing floor at the entrance of the gate of Samaria; and all the prophets prophesied before them.

10Now Zedekiah the son of Chenaanah had made horns of iron for himself; and he said, “Thus says the Lord: ‘With these you shall gore the Syrians until they are destroyed.’ ”

11And all the prophets prophesied so, saying, “Go up to Ramoth Gilead and prosper, for the Lord will deliver it into the king’s hand.”

12Then the messenger who had gone to call Micaiah spoke to him, saying, “Now listen, the words of the prophets with one accord encourage the king. Therefore please let your word be like the word of one of them, and speak encouragement.”
