1 Kings 22:10-12

10Dressed in royal attire, the king of Israel and Jehoshaphat king of Judah were sitting on their thrones at the threshing floor by the entrance of the gate of Samaria, with all the prophets prophesying before them.

11Now Zedekiah son of Chenaanah had made for himself iron horns and declared, “This is what the LORD says: ‘With these you shall gore the Arameans until they are finished off.’”

12And all the prophets were prophesying the same, saying, “Go up to Ramoth-gilead and triumph, for the LORD will deliver it into the hand of the king.”
