1 Kings 18:23

18:23 Let them bring us two bulls. Let them choose one of the bulls for themselves, cut it up into pieces, and place it on the wood. But they must not set it on fire. I will do the same to the other bull and place it on the wood. But I will not set it on fire.

1 Kings 18:32-38

18:32 With the stones he constructed an altar for the Lord. Around the altar he made a trench large enough to contain two seahs of seed. 18:33 He arranged the wood, cut up the bull, and placed it on the wood. 18:34 Then he said, “Fill four water jars and pour the water on the offering and the wood.” When they had done so, he said, “Do it again.” So they did it again. Then he said, “Do it a third time.” So they did it a third time. 18:35 The water flowed down all sides of the altar and filled the trench. 18:36 When it was time for the evening offering, Elijah the prophet approached the altar and prayed: “O Lord God of Abraham, Isaac, and Israel, prove today that you are God in Israel and that I am your servant and have done all these things at your command. 18:37 Answer me, O Lord, answer me, so these people will know that you, O Lord, are the true God and that you are winning back their allegiance.” 18:38 Then fire from the Lord fell from the sky. It consumed the offering, the wood, the stones, and the dirt, and licked up the water in the trench.
