‘Men of great stature’ in the Hebrew text is Nephilim. These ‘men of great stature,’ the Anakim, descended from Anak who descended from Arba (Joshua 5:13). Arba founded a city named Kiriath Arba, south of Canaan near Edom and Moab. In Genesis 9:25, Canaan was cursed by Noach because his father had exposed Noach’s nakedness as he slept off a drunken state. Some believe that Ham’s wife, and therefore Canaan, carried the Nephilim gene which is how they (the descendants of Canaan) were on the earth ‘after the flood.’
Nephilim is often translated ‘giant’s though a better definition would be ‘those who came down, those who descended or those who were cast down.” In the sense that they had spirit fathers and human mothers, they could be considered half-breeds. In the Sumerian cuniform, these beings were called Anunnaki.
