1 Kings 18:22-29 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. And when midday was past, they prophesied until the time of the offering of the evening sacrifice. But there was no voice; no one answered, no one paid attention.
1 Kings 19:1-2 And Ahab told Jezebel all that Elijah had done, also how he had executed all the prophets with the sword. Then Jezebel sent a messenger to Elijah, saying, “So let the gods do to me, and more also, if I do not make your life as the life of one of them by tomorrow about this time.”
1 Kings 18:19 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."
1 Kings 18:40 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.
