Genesis 6:1-5 (New American Standard Bible)

Genesis 6

The Corruption of Mankind

 ¹Now it came about, when men began to multiply on the face of the land, and daughters were born to them,

 ²that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose.

 ³Then the LORD said, "^(A)My Spirit shall not strive with man forever, ^(B)because he also is flesh; nevertheless his days shall be one hundred and twenty years."

 ⁴The ^(C)Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown.

 ⁵Then the LORD saw that the wickedness of man was great on the earth, and that ^(D)every intent of the thoughts of his heart was only evil continually.
