1 Kings 18:22-25

22Then Elijah said to them, “I am the only prophet of the Lord who is left, but Baal has 450 prophets.

23Now bring two bulls. The prophets of Baal may choose whichever one they wish and cut it into pieces and lay it on the wood of their altar, but without setting fire to it. I will prepare the other bull and lay it on the wood on the altar, but not set fire to it.

24Then call on the name of your god, and I will call on the name of the Lord. The god who answers by setting fire to the wood is the true God!” And all the people agreed.

25Then Elijah said to the prophets of Baal, “You go first, for there are many of you. Choose one of the bulls, and prepare it and call on the name of your god. But do not set fire to the wood.”
