Deuteronomy 2:20-23

20(That too was considered a land of the Rephaites, who used to live there; but the Ammonites called them Zamzummites. 21They were a people strong and numerous, and as tall as the Anakites. The Lord destroyed them from before the Ammonites, who drove them out and settled in their place. 22The Lord had done the same for the descendants of Esau, who lived in Seir, when he destroyed the Horites from before them. They drove them out and have lived in their place to this day. 23And as for the Avvites who lived in villages as far as Gaza, the Caphtorites coming out from Caphtor destroyed them and settled in their place.)
