1 Kings 18:30-35 KJV

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