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 The number of people on earth began to grow, and daughters were born to them.

2 When the sons of God saw that these girls were beautiful, they married any of them they chose.

3 The Lord said, "My Spirit will not remain in human beings forever, because they are flesh. They will live only 120 years."

4 The Nephilim were on the earth in those days and also later. That was when the sons of God had sexual relations with the daughters of human beings. These women gave birth to children, who became famous and were the mighty warriors of long ago.

5 The Lord saw that the human beings on the earth were very wicked and that everything they thought about was evil.
