1 Kings 18:21-23

21Then Elijah approached all the people and said, “How long will you waver between two opinions? If the LORD is God, follow Him. But if Baal is God, follow him.”

But the people did not answer a word.

22Then Elijah said to the people, “I am the only remaining prophet of the LORD, but Baal has four hundred and fifty prophets. 23Get two bulls for us. Let the prophets of Baal choose one bull for themselves, cut it into pieces, and place it on the wood but not light the fire. And I will prepare the other bull and place it on the wood but not light the fire.
