From an old thread:
Arba was a great man, possibly a contemporary of Abram, though I suspect a predecessor, who had not 'fallen' into depravity as his three 'nephilim' descendants had 400+yrs later.
I'm also considering another interpretation where Arba is not just one individual man.

Basically my idea is that because "arba" means fourth, and can also mean four, "Arba" is not one man, but four great men whose association set apart and gave name to the city Kirjath-arba(city of Arba)(city of Four), which later became Hebron(association).
The four men in association are the Hebrew Abram, and the Amorite brothers Aner, Eshcol, and Mamre. Their alliance kept the land from war until provoked by the war of four kings against five kings, at which point Abram, in league with the three Amorites, rose to pursue and defeat Chedorlaomer. Melchizedek, king of Salem, thought enough of their victory to come out to congratulate them. Abram refused tribute from Sodom, but allowed His colleagues to accept it, which probably contributed to the Amorites eventual downfall.
While Abrams descendant Israel left for Egypt to escape famine, the Amorite descendants stayed to fill their inequity. As the nation of Israel returned from captivity they found the descendants (Sheshai, Ahiman, Talmai) of the old allies of Abram (Mamre, Eshcol, Aner) intimidating in power, but fallen into depravity. Therefore the now fallen Amorites(nephilim) were to be judged by God through the Israelites for their transgressions.
So Amorites are now Nephilim?
Any scripture to back up your statement?
