1 Kings 18:34

And he said, do it the second time, and they did it the second time ,.... That is, poured four barrels of water more upon the wood:

and he said, do it the third time, and they did it the third time ; so that there were in all twelve barrels of water poured on the wood, agreeably to the number of the twelve stones the altar was built with, and may have respect to the same as they.
