1 Kings 18:30-35

30Then Elijah said to all the people, "Come near to me." And all the people came near to him. And 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,"

32and with the stones he built an altar in the name of the Lord. And he made a trench about the altar, as great as would contain two seahs of seed.

33And he put the wood in order and cut the bull in pieces and laid it on the wood. And he said, "Fill four jars with water and pour it on the burnt offering and on the wood."

34And he said, "Do it a second time." And they did it a second time. And he said, "Do it a third time." And they did it a third time.

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