Deuteronomy 2:20-23

20(That also was accounted a land of giants: giants dwelt there in times past; and the Ammonites call them Zamzummims;1 21A people great, and many, and tall, as the Anakims; but the LORD destroyed them before them; and they succeeded them, and dwelt in their stead: 22As he did to the children of Esau, who dwelt in Seir, when he destroyed the Horims from before them; and they succeeded them, and dwelt in their stead even to this day: 23And the Avims who dwelt in Hazerim, even to Azzah, the Caphtorims, who came forth from Caphtor, destroyed them, and dwelt in their stead.)
