The scriptures do not actually tell us if Goliath had six fingers and six toes. We learn much later in another war the Philistines had with Israel (2 Samuel 21:15-22 and 1 Chronicles 20:4-8) that there was “a man of great stature, that had on every hand six fingers, and on every foot six toes, four and twenty in number; and he was born to the giant.” (2 Samuel 21:20) He was, most likely, the son of Goliath and not Goliath himself.

The presence of an extra finger or toe is a very common congenital malformation (one in every 500 live human births) and has nothing to do with the progeny of the “fallen angels” since they were all destroyed in the Flood (Genesis 7:21-23) many years prior to the events mentioned above.

Is there any correlation between a giant with six digits on his hands and feet and the progeny of the “fallen angels”? No, there is no correlation.
