Deuteronomy 2:20-23

20(That also was accounted a land of giants: giants dwelt therein in old time; and the Ammonites call them Zamzummims;1

21A people great, and many, and tall, as the Anakims; But Yhwh destroyed them before them; and they succeeded them, and dwelt in their stead:

22As he did to the children of Esau, which dwelt in Seir, when he destroyed the Horims from before them; and they succeeded them, and dwelt in their stead even unto this day:

23And the Avims which dwelt in Hazerim, even unto Azzah, the Caphtorims, which came forth out of Caphtor, destroyed them, and dwelt in their stead.)
