'Trench' in the Bible

With the stones he built an altar in the name of Yahweh. He made a trench around the altar, large enough to contain two measures of seed.

The water ran around the altar; and he also filled the trench with water.

Then the fire of Yahweh fell, and consumed the burnt offering, and the wood, and the stones, and the dust, and licked up the water that was in the trench.
