Genesis 6:4-6

Expanded Bible

⁴ The ·Nephilim [^Lfallen ones; ^Cthe significance of the name is unclear] were on the earth in those days and also later. That was when the sons of God ·had sexual relations with [^Lcame in to] the daughters of ·human beings [^Tman; ^CHebrew: Adam; 1:27–28]. These women gave birth to children ·who became famous [^Lmen of a name] and were the mighty warriors of long ago. [^CThe Nephilim of Num. 13:31–33, though not related genealogically, were giants, suggesting these pre-flood Nephilim were also.]

⁵ The Lord saw that the human beings on the earth were very ·wicked [evil] and that ·everything they thought about [^Levery inclination of their mind/heart] was ·evil [wicked]. ⁶ He ·was sorry [regretted] he had made human beings on the earth, and his heart was filled with pain.
