1 Kings 18:17-20

17When Ahab saw Elijah, Ahab said to him, "Is it you, you troubler of Israel?"

18And he answered, "I have not troubled Israel, but you have, and your father's house, because you have abandoned the commandments of the Lord and followed the Baals.

19Now therefore send and gather all Israel to me at Mount Carmel, and the 450 prophets of Baal and the 400 prophets of Asherah, who eat at Jezebel's table."

20So Ahab sent to all the people of Israel and gathered the prophets together at Mount Carmel.
