Interesting. Because I was just wondering about that because of David and Goliath for instance which was after the flood. So the question is, what was the decendency of Goliath if the lineage was destroyed by the flood.
Again, since this area is unfamilar to me, I consult my study Bible.
Genesis 6:4
Thete were giants in the Earth in those days (as a result of the union of the fallen angels with the “daughters of men”); and also after that (”those days” speak of the time before the flood, while “also after that” speaks of the time after the flood; in fact, Goliath, who was killed by David, was one of those specimens), when the sons of God came in unto the daughters of men, and they bore children to them, the same became mighty men which were of old, men of renown (these terms, “mighty men, men of renown” shoot down the hypothesis of these terms referring merely to the lineage of Seth and the lineage of Cain).
Goliath’s stature is described in the Dead Sea Scrolls text of Samuel, the 1st-century historian Josephus and the 4th-century Septuagint manuscripts as “four cubits and a span” (6 feet 9 inches or 2.06 metres).
After Israel moved to the promised land anyone of giant stature was called a Nephilim
