1 Kings 18:30-40King James Version (KJV)
30 And Elijah said unto all the people, Come near unto me. And all the people came near unto him. And he repaired the altar of the Lord that was broken down.
31 And Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, unto whom the word of the Lord came, saying, Israel shall be thy name:
32 And 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.
33 And 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.
34 And 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.
35 And the water ran round about the altar; and he filled the trench also with water.
36 And 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.
37 Hear 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.
38 Then 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.
39 And 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.
40 And 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.
