Genesis 6:1-5 New King James Version (NKJV)
The Wickedness and Judgment of Man
6 Now it came to pass, when men began to multiply on the face of the earth, and daughters were born to them, 2 that the sons of God saw the daughters of men, that they were beautiful; and they took wives for themselves of all whom they chose.
3 And the Lord said, “My Spirit shall not strive[a] with man forever, for he is indeed flesh; yet his days shall be one hundred and twenty years.” 4 There were [b]giants 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.

Genesis 6:1-5 Young's Literal Translation (YLT)
6 And it cometh to pass that mankind have begun to multiply on the face of the ground, and daughters have been born to them,
2 and sons of God see the daughters of men that they [are] fair, and they take to themselves women of all whom they have chosen.
3 And Jehovah saith, `My Spirit doth not strive in man -- to the age; in their erring they [are] flesh:' and his days have been an hundred and twenty years.
4 The fallen ones were in the earth in those days, and even afterwards when sons of God come in unto daughters of men, and they have borne to them -- they [are] the heroes, who, from of old, [are] the men of name.
5 And Jehovah seeth that abundant [is] the wickedness of man in the earth, and every imagination of the thoughts of his heart only evil all the day;

The Corruption of Mankind
6 Now it came about, when men began to multiply on the face of the land, and daughters were born to them, 2 that the sons of God saw that the daughters of men were [a]beautiful; and they took wives for themselves, whomever they chose. 3 Then the Lord said, “My Spirit shall not [b]strive with man forever, [c]because he also is flesh; [d]nevertheless his days shall be one hundred and twenty years.” 4 The 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.
5 Then the Lord saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was only evil continually.
