1 Kings 18:18-21

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.

21And Elijah came near to all the people and said, "How long will you go limping between two different opinions? If the Lord is God, follow him; but if Baal, then follow him." And the people did not answer him a word.
