Deuteronomy 2:16-20

16When the last of these soldiers had died,

17the Lord said to me,

18“Today you are going to pass by the border of Moab at Ar.

19When you come near the Ammonites, don’t bother them or start a fight with them. I’m not giving you any of the land that I have already given to the descendants of Lot as their property.”

20This land was thought of as the land of the Rephaim who used to live there, but the Ammonites called them Zamzummim.
