1 Kings 22:10-12

10Now the king of Israel and Jehoshaphat king of Judah were sitting each on his throne, arrayed in their robes, at the threshing floor at the entrance of the gate of Samaria; and 1all the prophets were prophesying before them. 11Then Zedekiah the son of Chenaanah made 2horns of iron for himself and said, “Thus says the Lord, ‘3With these you will gore the Arameans until they are consumed.’” 12All the prophets were prophesying thus, saying, “Go up to Ramoth-gilead and prosper, for the Lord will give it into the hand of the king.”
