1 Kings 18:30-37

Then Elijah said to all the people, “Now come to me.” So they gathered around him, and Elijah rebuilt the altar of the LORD, which had been torn down. He took twelve stones, one stone for each of the twelve tribes, the number of Jacob’s sons. (The LORD changed Jacob’s name to Israel.) Elijah used these stones to rebuild the altar in honor of the LORD. Then he dug a ditch around the altar that was big enough to hold about thirteen quarts of seed. Elijah put the wood on the altar, cut the bull into pieces, and laid the pieces on the wood. Then he said, “Fill four jars with water, and pour it on the meat and on the wood.” Then Elijah said, “Do it again,” and they did it again. Then he said, “Do it a third time,” and they did it the third time. So the water ran off the altar and filled the ditch. At the time for the evening sacrifice, the prophet Elijah went near the altar. “LORD, you are the God of Abraham, Isaac, and Israel,” he prayed. “Prove that you are the God of Israel and that I am your servant. Show these people that you commanded me to do all these things. LORD, answer my prayer so these people will know that you, LORD, are God and that you will change their minds.”
