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 Then the people began to multiply on the earth, and daughters were born to them.

2 The sons of God saw the beautiful women and took any they wanted as their wives.

3 Then the LORD said, “My Spirit will not put up with humans for such a long time, for they are only mortal flesh. In the future, their normal lifespan will be no more than 120 years.”

4 In those days, and for some time after, giant Nephilites lived on the earth, for whenever the sons of God had intercourse with women, they gave birth to children who became the heroes and famous warriors of ancient times.

5 The LORD observed the extent of human wickedness on the earth, and he saw that everything they thought or imagined was consistently and totally evil.
