1 Kings 18:32-35

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 seahs of seed. And he put the wood in order and cut the bull in pieces and laid it on the wood. And he said, “Fill four jars with water and pour it on the burnt offering and on the wood.” And 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. And the water ran around the altar and filled the trench also with water.
