1 Kings 18:30-36

30Then Elijah said to all the people, “Come here to me.” They came to him, and he repaired the altar of the Lord, which had been torn down. 31Elijah took twelve stones, one for each of the tribes descended from Jacob, to whom the word of the Lord had come, saying, “Your name shall be Israel.” 32With the stones he built an altar in the name of the Lord, and he dug a trench around it large enough to hold two seahs of seed. 33He arranged the wood, cut the bull into pieces and laid it on the wood. Then he said to them, “Fill four large jars with water and pour it on the offering and on the wood.” 34“Do it again,” he said, and they did it again. “Do it a third time,” he ordered, and they did it the third time. 35The water ran down around the altar and even filled the trench. 36At the time of sacrifice, the prophet Elijah stepped forward and prayed: “Lord, the God of Abraham, Isaac and Israel, let it be known today that you are God in Israel and that I am your servant and have done all these things at your command.
