22 And they ascended by the south , and came unto Hebron: where Ahiman, Sheshai, and Talmai, the children of Anak were: (now Hebron was built seven years before Zoan in Egypt )

A famous giant so called, whose children these are called, either more generally, as all giants sometimes were, or rather more specially, because Arbah, from whom Hebron was called Kiriath-arbah, was the father of Anak, Ios. 15. 13. And this circumstance is mentioned as an evidence of the goodness of that land and soil, because the giants chose it for their habitation.

u This seems to be noted to confront the Egyptians who vainly boasted of the antiquity of their city Zoan above all places.
