Giant humans (Nephilim) arise after the flood.
We have previously established how, before the flood, human DNA was corrupted when angels married and bore children through human women.
These original giants, known as Nephilim, were evil, violent warriors. Their wickedness, Scripture indicates, was a major influence in the spread of evil leading to GOD's decision to flood the world and start over.
While Noah and his wife were of pure human DNA, Noah's son Ham's wife apparently had polluted angelic-human blood. For as soon as the Genesis account of Noah's genealogy begins, we see a return of the giant Nephilim.
1 Now this is the genealogy of Noah's sons: Shem, Ham, and Japheth, and sons were born to them after the flood.
2 The sons of Japheth were Gomer, Magog, Madai, Javan, Elisa, Tubal, Meshech, and Tiras.
3 The sons of Gomer were Ashkenaz, Riphath, and Togarmah. 4 The sons of Javan were Elishah, Tarshish, the Kittim, and Rhodians. 5 From these the coastal nations were separated into their lands, each according to his language, in their tribes and nations.
6 The sons of Ham were Cush, Mizraim, Put, and Canaan. 7 The sons of Cush were Seba, Havilah, Sabtah, Raamah, and Sabtechah; and the sons of Raamah were Sheba and Dedan.
8 Cush begot Nimrod; he began to be a giant on the earth. 9 He was a giant, a hunter before the Lord God; therefore they would say, “As Nimrod the giant, the hunter before the Lord.”
10 And the beginning of his kingdom was Babylon, Erech, Accad, and Calneh, in the land of Shinar. 11 From that land he went to Assyria and built Nineveh, Rehoboth Ir, Calah, 12 and Resen between Nineveh and Calah (the principal city). 13 Mizraim begot Ludim, Anamim, Lehabim, Naphtuhim, 14 Pathrusim, and Casluhim (from whom came the Philistines and the Caphtorim). 15 Canaan begot Sidon his firstborn, and the Chettite; 16 the Jebusite, the Amorite, and the Girgashite; 17 the Hivite, the Arkite, and the Sinite; 18 the Arvadite, the Zemarite, and the Hamathite. Afterward, the tribes of the Canaanites were dispersed. 19 And the border of the Canaanites was from Sidon as you go toward Gerar, as far as Gaza; then as you go toward Sodom, Gomorrah, Admah, and Zeboiim, as far as Lasha. 20 These were the sons of Ham, according to their tribes, according to their languages, in their countries and in their nations.
(Genesis 10:1-20 OSB)
Let's take a quick inventory of Ham's descendants' influence:
- Nimrod is the first post-flood giant (Nephilim).
- Nimrod founded the ancient city of Nineveh and the Babylonian kingdom.
- Mizraim is the forefather of the Philistines, from whom came the famous giant Goliath who was defeated by David.
- Canaan is the forefather of the Canaanites, whose wickedness brought GOD to use Israel to punish and largely destroy.
- The Canaanites appear to have been the original builders of Sodom and Gomorrah, the wicked cities GOD destroyed during Abraham's lifetime.
Most of the post-flood biblical references to giants (Nephilim) were Canaanites, but all of them were descendants of Ham. There is no biblical evidence that angels mated with human women again after the flood. Therefore, we must conclude that the post-flood giants were the result of Ham's wife being of partially-angelic descent.
These post-flood Nephilim play a big role in the Bible story.
