Numbers 13:28

Nevertheless the people be strong that dwell in the land, and the cities are walled, and very great: and moreover we saw the children of Anak there.

We saw the children of Anak there. Accustomed to the Egyptians, who, as may be inferred from their mummies, were slight and short of stature, rather puny, the tall muscular appearance of the mountaineers of Hebron must, to the Israelites, have formed a striking contrast. No wonder that they inspired terror; because, combined with an extraordinary stature, they were a fierce, wild, wicked race, engaged in continual warfare. Their gigantic appearance arose from their being distinguished by unusually long necks, like the Patagonians of South America; who are noted for their personal deformity-the upper part of their bodies being of disproportionate length.
