Parallel
Genesis 6:4
Brenton's English Septuagint · Berean Standard Bible
Now the giants were upon the earth in those days; and after that when the sons of God were wont to go in to the daughters of men, they bore [children] to them, those were the giants of old, the men of renown.
The Nephilim were on the earth in those days—and afterward as well—when the sons of God had relations with the daughters of men. And they bore them children who became the mighty men of old, men of renown.
