1 Kings 22:10-12

10The king of Israel and King Jehoshaphat of Judah were dressed in royal robes and seated on thrones. They were on the threshing floor  at the entrance to the gate of Samaria. All the prophets were prophesying in front of them.

11Zedekiah, son of Chenaanah, made iron horns and said, “This is what the Lord says: With these horns you will push the Arameans to their destruction.”

12All the other prophets made the same prophecy. They said, “Attack Ramoth in Gilead, and you will win. The Lord will hand it over to you.”
