16 Then he said, “This is what the Lord says: ‘Dig ditch after ditch in this wadi.’
17 For the Lord says, ‘You will not see wind or rain, but the wadi will be filled with water, and you will drink — you and your cattle and your animals.’
18 This is easy in the Lord’s sight. He will also hand Moab over to you.
19 Then you must attack every fortified city and every choice city. You must cut down every good tree and stop up every spring of water. You must ruin every good piece of land with stones.”
20 About the time for the grain offering the next morning, water suddenly came from the direction of Edom and filled the land.
21 All Moab had heard that the kings had come up to fight against them. So all who could bear arms, from the youngest to the oldest, were summoned and took their stand at the border.
22 When they got up early in the morning, the sun was shining on the water, and the Moabites saw that the water across from them was red like blood.
