I Kings 18:32-35

Then with the stones he built an altar in the name of the LORD; and he made a trench around the altar large enough to hold two seahs of seed. And he put the wood in order, cut the bull in pieces, and laid it on the wood, and said, “Fill four waterpots with water, and pour it on the burnt sacrifice and on the wood.” Then he said, “Do it a second time,” and they did it a second time; and he said, “Do it a third time,” and they did it a third time. So the water ran all around the altar; and he also filled the trench with water.
