The popular story of David and Goliath describes Goliath as very tall ("six cubits and a span"--apparently roughly 9 feet 9 inches, or 297cm). Most children are just told he was a "giant" in Sunday school.
Where did he come from? Was he part of a now-extinct race of giants, or was it just some sort of genetic mutation?
In the beginning...
The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
The descendants of these children of Nephilim were the giants that show up later in the bible. When Moses sent the twelve spies into Canaan, the promised land (before the 40 years of wandering), they reported back of giants in the land:
We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.”
There's another reference to them in 2 Samuel:
In still another battle, which took place at Gath, there was a huge man with six fingers on each hand and six toes on each foot—twenty-four in all. He also was descended from Rapha.
Goliath, himself, was a Philistine. He was also known as the "Goliath of Gath". Gath was one of the five city-states of Philistine.
As he was talking with them, Goliath, the Philistine champion from Gath, stepped out from his lines and shouted his usual defiance, and David heard it.
Because we know that Goliath was from Gath (from 1 Samuel) and that the giants in Gath were descendants of the Nephilim (from 2 Samuel) it's pretty safe to assume he was one of those.
It's also safe to assume some possible genetic issues (due to the six fingers and toes).
genesis 6:4 The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
Angels went into women before flood god wiped thm out with flood then they came and did it again afterward god promised he wouldnt flood world again and so sent Isreal to destroy them when they entered promised land.
Total speculation here but I believe the giants descended from Canaan, the son of Ham. It is possible that the wives of Noah's sons were not genetically pure as the Bible indicates of Noah. Roman-Jewsish historian Josephus mentioned a man named Amorreus, who was allegedly a son of Canaan, as well as the father of the Amorites. If I'm not mistaken King Og of Bashan was an Amorite.
I believe that the gene of the giants were passed down after the flood through Ham, to his son Mizraim,which are the Philistine peoples.
