1 Kings 18:22-28

Then Elijah said to them, “I am the only prophet of the LORD who is left, but Baal has 450 prophets. Now 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. Then 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. Then 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.” So they prepared one of the bulls and placed it on the altar. Then they called on the name of Baal from morning until noontime, shouting, “O Baal, answer us!” But there was no reply of any kind. Then they danced, hobbling around the altar they had made. About noontime Elijah began mocking them. “You’ll have to shout louder,” he scoffed, “for surely he is a god! Perhaps he is daydreaming, or is relieving himself. Or maybe he is away on a trip, or is asleep and needs to be wakened!” So they shouted louder, and following their normal custom, they cut themselves with knives and swords until the blood gushed out.
