Deuteronomy 2:16-22

16“Now when all the men of war had finished dying from among the people,

17Adonai spoke to me saying,

18‘Today you are about to cross the border of Moab at Ar.

19When you come opposite the sons of Ammon, do not harass or provoke them—for I will not give you any of the land of the sons of Ammon for a possession, because I have given it to the sons of Lot for a possession.

20(That also is considered a land of Rephaim. Rephaim used to live there, but the Ammonites call them Zamzummim—

21a great and numerous people, as tall as the Anakim. But Adonai destroyed them from before them, and the Ammonites dispossessed them and settled in their place.

22It was just as Adonai did for the sons of Esau, who dwell in Seir, when He destroyed the Horites before them. They drove them out and settled in their place even to this day.
