1 Kings 18:30-35

30Then Elijah said to all the people, “Come near me.” So all the people approached him. Then he repaired the Lord’s altar that had been torn down:

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

32and he built an altar with the stones in the name of the Lord. Then he made a trench around the altar large enough to hold about four gallons.

33Next, he arranged the wood, cut up the bull, and placed it on the wood. He said, “Fill four water pots with water and pour it on the offering to be burned and on the wood.”

34Then he said, “A second time!” and they did it a second time. And then he said, “A third time!” and they did it a third time.

35So the water ran all around the altar; he even filled the trench with water.
