1 Kings 22:10-12

10Now the king of Israel and Jehoshaphat the king of Judah were sitting, each on his throne, dressed 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, “This is what the Lord says: ‘3With these you will gore the Arameans until they are destroyed!’” 12All the prophets were prophesying this as well, saying, “Go up to Ramoth-gilead and succeed, for the Lord will hand it over to the king.”
