NIV Calls Nephilim (Demons) "Heroes"
The New International Version (NIV), Gen. 6:4 "The Nephilim were on the earth in those days--and also afterward--when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown."
The King James Version: Gen. 6:4, "There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became
mighty men which were of old, men of renown."
