'Son of God' in the Bible

Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession.

and then have fallen away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put him to an open shame.

Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest continually.

How much severer punishment do you think a man will deserve who has trampled under foot the Son of God, and has regarded as an unclean thing the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
