Genesis 6:1-8
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 with man forever,
for he isindeed flesh; yet his days shall be one hundred and twenty
years.” 4 There were 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.

5 Then the Lord saw that the wickedness of
man was great in the earth, andthat every intent of the thoughts of
his heart was only evil continually. 6 And
theLord was sorry that He had made man on the earth, and He
was grieved in His heart. 7 So the Lord said, “I will destroy man whom I have created from the
face of the earth, both man and beast, creeping thing and birds of the air, for I am sorry that
I have made them.” 8 But Noah found grace in the eyes
of the Lord.
