19 You will capture all their walled cities and important towns. You will chop down every good tree and stop up every spring of water, then ruin their fertile fields by covering them with rocks.
20 The next morning, while the sacrifice was being offered, water suddenly started flowing from the direction of Edom, and it flooded the land.
