Numbers 13:22

And they ascended by the south, after leaving the camp of the Israelites, and came unto Hebron; where Ahiman, Sheshai, and Talmai, the children of Anak, were. (Now Hebron was built seven years before Zoan in Egypt.) These three princes of the Anakim were descendants of Arbah, the founder of Hebron, for its original name was Kiriath-arbah. This was a very old city, as Moses indicates by comparing its age with that of Zoan in Egypt, which the children of Israel knew so well.
