1 Kings 18:30-35

30Then Elijah said to all the people, “Come near to me.” So all the people came closer to him. Then he repaired the damaged altar of Adonai.

31Elijah took twelve stones—like the number of the tribes of the sons of Jacob, to whom the word of Adonai had come saying, “Israel shall be your name”—

32and with the stones he built an altar in the Name of Adonai. Then he made a trench around the altar, large enough to contain two measures of seed.

33Then he put the wood in order, cut the bull in pieces and laid it on the wood.

34Then he said, “Fill four jars with water and pour it on the burnt offering and on the wood.” Then he said, “A second time!” and they did it a second time. Then he said, “A third time!” and they did it a third time.

35So the water ran around the altar and he also filled the trench with water.
