1 Kings 18:31 (KJV)

And it came to pass, when midday was past, and they prophesied until the time of the offering of the evening sacrifice, that there was neither voice, nor any to answer, nor any that regarded.

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.

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:

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.

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.
