2 Kings 3:16-20

16And he said, Thus saith Yhwh, Make this valley full of ditches.

17For thus saith Yhwh, Ye shall not see wind, neither shall ye see rain; yet that valley shall be filled with water, that ye may drink, both ye, and your cattle, and your beasts.

18And this is but a light thing in the sight of Yhwh: he will deliver the Moabites also into your hand.

19And ye shall smite every fenced city, and every choice city, and shall fell every good tree, and stop all wells of water, and mar every good piece of land with stones.1

20And it came to pass in the morning, when the grain offering was offered, that, behold, there came water by the way of Edom, and the country was filled with water.
