Genesis 6:1 Meaning and Commentary

Genesis 6:1

And it came to pass, when men began to multiply upon the
face of the earth
Either mankind in general, or rather the posterity of Cain, who were mere natural men, such as they were when born into the world, and as brought up in it, destitute of the grace of God, and of the knowledge and fear of him; and who in proportion much more multiplied than the posterity of Seth, because of the practice of polygamy, which by the example of Lamech, one of that race, might prevail among them: and daughters were born unto them;
not daughters only, but sons also, though it may be more daughters than sons, or it may denote remarkable ones, for their beauty or immodesty, or both; and chiefly this is observed for the sake of what follows.

Genesis 6:1 In-Context

1 It happened, when men began to multiply on the surface of the ground, and daughters were born to them,

2 that God's sons saw that men's daughters were beautiful, and they took for themselves wives of all that they chose.

3 Yahweh said, "My spirit will not strive with man forever, because he also is flesh; yet will his days be one hundred twenty years."

4 The Nephilim were in the earth in those days, and also after that, when God's sons came to men's daughters. They bore children to them: the same were the mighty men who were of old, men of renown.

5 Yahweh saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
