1 Kings 18:20-24, 36-40

So Ahab sent to all the people of Israel and gathered the prophets together at Mount Carmel. And Elijah came near to all the people and said, “How long will you go limping between two different opinions? If the LORD is God, follow him; but if Baal, then follow him.” And the people did not answer him a word. Then Elijah said to the people, “I, even I only, am left a prophet of the LORD, but Baal’s prophets are 450 men. Let two bulls be given to us, and let them choose one bull for themselves and cut it in pieces and lay it on the wood, but put no fire to it. And I will prepare the other bull and lay it on the wood and put no fire to it. And you call upon the name of your god, and I will call upon the name of the LORD, and the God who answers by fire, he is God.” And all the people answered, “It is well spoken.”

And at the time of the offering of the oblation, Elijah the prophet came near and said, “O LORD, God of Abraham, Isaac, and Israel, let it be known this day that you are God in Israel, and that I am your servant, and that I have done all these things at your word. Answer me, O LORD, answer me, that this people may know that you, O LORD, are God, and that you have turned their hearts back.” Then the fire of the LORD fell and consumed the burnt offering and the wood and the stones and the dust, and licked up the water that was in the trench. And when all the people saw it, they fell on their faces and said, “The LORD, he is God; the LORD, he is God.” And Elijah said to them, “Seize the prophets of Baal; let not one of them escape.” And they seized them. And Elijah brought them down to the brook Kishon and slaughtered them there.
