1Kgs 18:30-35

30Then Elijah said to all the people, “Come closer to me”; and all the people came closer to him. First he repaired the altar of the Lord that had been thrown down;31Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, to whom the word of the Lord came, saying, “Israel shall be your name”;32with the stones he built an altar in the name of the Lord. Then he made a trench around the altar, large enough to contain two measures of seed.33Next he put the wood in order, cut the bull in pieces, and laid it on the wood. He said, “Fill four jars with water and pour it on the burnt offering and on the wood.”34Then he said, “Do it a second time”; and they did it a second time. Again he said, “Do it a third time”; and they did it a third time,35so that the water ran all around the altar, and filled the trench also with water.
