1 Kings 18:35

31Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, to whom the LORD’s word came, saying, “Israel shall be your name.”

32With the stones he built an altar in the LORD’s name. He made a trench around the altar large enough to contain two seahs of seed.

33He put the wood in order, and 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.”

34He said, “Do it a second time;” and they did it the second time. He said, “Do it a third time;” and they did it the third time.

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

36At the time of the evening offering, Elijah the prophet came near and said, “LORD, the God of Abraham, of Isaac, and of Israel, let it be known today that you are God in Israel and that I am your servant, and that I have done all these things at your word.

37Hear me, LORD, hear me, that this people may know that you, LORD, are God, and that you have turned their heart back again.”

38Then the LORD’s fire fell and consumed the burnt offering, the wood, the stones, and the dust; and it licked up the water that was in the trench.

39When all the people saw it, they fell on their faces. They said, “The LORD, he is God! The LORD, he is God!”
