2 Kings 3:16-20

3:16 and he said, “This is what the Lord says, ‘Make many cisterns in this valley,’ 3:17 for this is what the Lord says, ‘You will not feel any wind or see any rain, but this valley will be full of water and you and your cattle and animals will drink.’ 3:18 This is an easy task for the Lord; he will also hand Moab over to you. 3:19 You will defeat every fortified city and every important city. You must chop down every productive tree, stop up all the springs, and cover all the cultivated land with stones.”

3:20 Sure enough, the next morning, at the time of the morning sacrifice, water came flowing down from Edom and filled the land.
