1 Kings 18:21-24

21Elijah approached all the people and said, “How long will you hesitate between two opinions? If the Lord is God, follow Him; but if Baal, follow him.” But the people [of Israel] did not answer him [so much as] a word.

22Then Elijah said to the people, “I alone remain a prophet of the Lord, while Baal’s prophets are 450 men.

23Now let them give us two oxen, and let them choose one ox for themselves and cut it in pieces, and lay it on the wood, but put no fire under it. I will prepare the other ox and lay it on the wood, and I will not put a fire under it.

24Then you call on the name of your god, and I will call on the name of the Lord; and the god who answers by fire, He is God.” And all the people answered, “It is well spoken.”
