1 Kings 18:36-38

At the hour of the afternoon sacrifice the prophet Elijah approached the altar and prayed, “O LORD, the God of Abraham, Isaac, and Jacob, prove now that you are the God of Israel and that I am your servant and have done all this at your command. Answer me, LORD, answer me, so that this people will know that you, the LORD, are God, and that you are bringing them back to yourself.” The LORD sent fire down, and it burnt up the sacrifice, the wood, and the stones, scorched the earth and dried up the water in the trench.
