1 Kings 22:9-11

Then the king of Israel called an officer, and said, Hasten {hither} Micaiah the son of Imlah. {officer: or, eunuch} And the king of Israel and Jehoshaphat the king of Judah sat each on his throne, having put on their robes, in a void place in the entrance of the gate of Samaria; and all the prophets prophesied before them. {void...: Heb. floor} And Zedekiah the son of Chenaanah made him horns of iron: and he said, Thus saith the LORD, With these shalt thou push the Syrians, until thou have consumed them.
