1 Kings 18:36

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 measures of seed.

33And he put the wood in order, and cut the bullock in pieces, and laid him on the wood, and said, Fill four barrels with water, and pour it on the burnt sacrifice, and on the wood.

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

35And the water ran round about the altar; and he filled the trench also with water.

36And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, Lord God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word.

37Hear me, O Lord, hear me, that this people may know that thou art the Lord God, and that thou hast turned their heart back again.

38Then the fire of the Lord fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench.

39And when all the people saw it, they fell on their faces: and they said, The Lord, he is the God; the Lord, he is the God.

40And Elijah said unto them, Take the prophets of Baal; let not one of them escape. And they took them: and Elijah brought them down to the brook Kishon, and slew them there.
