the LORD said to me, ‘Today you are to cross the border of Moab at Ar. And when you approach the territory of the people of Ammon, do not harass them or contend with them, for I will not give you any of the land of the people of Ammon as a possession, because I have given it to the sons of Lot for a possession.’ (It is also counted as a land of Rephaim. Rephaim formerly lived there—but the Ammonites call them Zamzummim— a people great and many, and tall as the Anakim; but the LORD destroyed them before the Ammonites, and they dispossessed them and settled in their place, as he did for the people of Esau, who live in Seir, when he destroyed the Horites before them and they dispossessed them and settled in their place even to this day. As for the Avvim, who lived in villages as far as Gaza, the Caphtorim, who came from Caphtor, destroyed them and settled in their place.)
