2 Kings 3:16-20

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

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

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

19And ye shall smite every fortified 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.

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