I Kings 18:18-21, 25-28, 40

And he answered, “I have not troubled Israel, but you and your father’s house have, in that you have forsaken the commandments of the LORD and have followed the Baals. Now therefore, send and gather all Israel to me on Mount Carmel, the four hundred and fifty prophets of Baal, and the four hundred prophets of Asherah, who eat at Jezebel’s table.” So Ahab sent for all the children of Israel, and gathered the prophets together on Mount Carmel. And Elijah came to all the people, and said, “How long will you falter between two opinions? If the LORD is God, follow Him; but if Baal, follow him.” But the people answered him not a word.

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.

And Elijah said to them, “Seize the prophets of Baal! Do not let one of them escape!” So they seized them; and Elijah brought them down to the Brook Kishon and executed them there.
