'Sons of God' in the Bible

the sons of God saw that the daughters of mankind were beautiful, and they took any they chose as wives for themselves.

The Nephilim were on the earth both in those days and afterward, when the sons of God came to the daughters of mankind, who bore children to them. They were the powerful men of old, the famous men.

One day the sons of God came to present themselves before the Lord, and Satan also came with them.

One day the sons of God came again to present themselves before the Lord, and Satan also came with them to present himself before the Lord.

while the morning stars sang togetherand all the sons of God shouted for joy?
