1 Kings 18:24

20 So Ahab summoned all the Israelites and assembled the prophets on Mount Carmel.

21 Then Elijah approached all the people and said, “How long will you waver between two opinions? If the LORD is God, follow Him. But if Baal is God, follow him.” But the people did not answer a word.

22 Then Elijah said to the people, “I am the only remaining prophet of the LORD, but Baal has four hundred and fifty prophets.

23 Get two bulls for us. Let the prophets of Baal choose one bull for themselves, cut it into pieces, and place it on the wood but not light the fire. And I will prepare the other bull and place it on the wood but not light the fire.

24 Then you may call on the name of your god, and I will call on the name of the LORD. The God who answers by fire, He is God.” And all the people answered, “What you say is good.”

25 Then Elijah said to the prophets of Baal, “Since you are so numerous, choose for yourselves one bull and prepare it first. Then call on the name of your god, but do not light the fire.”

26 And they took the bull that was given them, prepared it, and called on the name of Baal from morning until noon, shouting, “O Baal, answer us!” But there was no sound, and no one answered as they leaped around the altar they had made.

27 At noon Elijah began to taunt them, saying, “Shout louder, for he is a god! Perhaps he is deep in thought, or occupied, or on a journey. Perhaps he is sleeping and must be awakened!”

28 So they shouted louder and cut themselves with knives and lances, as was their custom, until the blood gushed over them.
