Genesis 6:2-4

New International Version

² the sons of God^(A) saw that the daughters^(B) of humans were beautiful,^(C) and they married^(D) any of them they chose. ³ Then the Lord said, “My Spirit^(E) will not contend with^[a] humans forever,^(F) for they are mortal^[b];^(G) their days will be a hundred and twenty years.”

⁴ The Nephilim^(H) were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans^(I) and had children by them. They were the heroes of old, men of renown.^(J)
