Genesis 6:1-8

NKJV
New King James Version

1Now it came to pass, #Gen. 1:28when men began to multiply on the face of the earth, and daughters were born to them, 2that the sons of God saw the daughters of men, that they were beautiful; and they #Deut. 7:3, 4took wives for themselves of all whom they chose.
3And the Lord said, #Gen. 41:38; (Gal. 5:16, 17); 1 Pet. 3:19, 20“My Spirit shall not #2 Thess. 2:7strive with man forever, #Ps. 78:39for he is indeed flesh; yet his days shall be one hundred and twenty years.” 4There were giants on the earth in those #Num. 13:32, 33; Luke 17:27days, 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 in the earth, and that every #Gen. 8:21; Ps. 14:1–3; Prov. 6:18; Matt. 15:19; Rom. 1:28–32intent of the thoughts of his heart was only evil continually. 6And #Gen. 6:7; 1 Sam. 15:11, 29; 2 Sam. 24:16; Jer. 18:7–10; Zech. 8:14the Lord was sorry that He had made man on the earth, and #Ps. 78:40; Is. 63:10; Eph. 4:30He was grieved in His #Mark 3:5heart. 7So the Lord said, “I will #Gen. 7:4, 23; Deut. 28:63; 29:20; Ps. 7:11destroy 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.” 8But Noah #Gen. 19:19; Ex. 33:12, 17; Luke 1:30; Acts 7:46found grace in the eyes of the Lord.
