Deuteronomy 2:20-23

MKJV(i) 20 It also was known to be a land of giants. Giants lived there in past times. And the Ammonites call them Zamzumim, 21 a great and plentiful people, and tall, like the sons of Anak, but Jehovah destroyed them before them. And they expelled them and lived in their place, 22 as He did to the sons of Esau who lived in Seir, when he destroyed the Horim from before them. And they expelled them and lived in their place even to this day. 23 And the Avvim who lived in villages as far as Azzah, the Caphtorites, who came forth out of Caphtor destroyed them, and lived in their place.
