I Kings 18:22-28

Then Elijah said to the people, “I alone am left a prophet of the LORD; but Baal’s prophets are four hundred and fifty men. Therefore let them give us two bulls; and let them choose one bull for themselves, cut it in pieces, and lay it on the wood, but put no fire under it; and I will prepare the other bull, and lay it on the wood, but put no fire under it. Then you call on the name of your gods, and I will call on the name of the LORD; and the God who answers by fire, He is God.” So all the people answered and said, “It is well spoken.” Now Elijah said to the prophets of Baal, “Choose one bull for yourselves and prepare it first, for you are many; and call on the name of your god, but put no fire under it.” So they took the bull which was given them, and they prepared it, and called on the name of Baal from morning even till noon, saying, “O Baal, hear us!” But there was no voice; no one answered. Then they leaped about the altar which they had made. And so it was, at noon, that Elijah mocked them and said, “Cry aloud, for he is a god; either he is meditating, or he is busy, or he is on a journey, or perhaps he is sleeping and must be awakened.” So they cried aloud, and cut themselves, as was their custom, with knives and lances, until the blood gushed out on them.
