Bereshis 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.

Bereshis 6:1 In-Context

1 And it came to pass, when HaAdam began to multiply on the face of ha’adamah, and banot were born unto them,

2 That the bnei HaElohim saw the banot HaAdam that they were tovot; and they took them nashim of all which they chose.

3 And Hashem said, My Ruach [Hakodesh] shall not always strive with Adam, for that he also is basar: yet his yamim shall be a hundred and twenty shanah.

4 HaNefilim were on ha’aretz in those yamim; and also after that, when the bnei HaElohim came in unto the banot HaAdam, and they bore children to them, the same became gibborim which were of old, men of renown.

5 And Hashem saw that the wickedness of HaAdam was great in ha’aretz and that every yetzer (inclination) of the machshevot (thoughts) of his lev was only rah (evil) continually.
