1 Kings 18:36-41

At the usual time for offering the evening sacrifice, Elijah the prophet walked up to the altar and prayed, “O LORD, God of Abraham, Isaac, and Jacob, prove today that you are God in Israel and that I am your servant. Prove that I have done all this at your command. O LORD, answer me! Answer me so these people will know that you, O LORD, are God and that you have brought them back to yourself.” Immediately the fire of the LORD flashed down from heaven and burned up the young bull, the wood, the stones, and the dust. It even licked up all the water in the trench! And when all the people saw it, they fell face down on the ground and cried out, “The LORD—he is God! Yes, the LORD is God!” Then Elijah commanded, “Seize all the prophets of Baal. Don’t let a single one escape!” So the people seized them all, and Elijah took them down to the Kishon Valley and killed them there. Then Elijah said to Ahab, “Go get something to eat and drink, for I hear a mighty rainstorm coming!”
