(28) He that despised Moses' law died without mercy under two or three witnesses: (29) Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden underfoot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? (30) For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people. (31) It is a fearful thing to fall into the hands of the living God.
In following up the same subject, Paul here very strikingly reminds the Heb 1-13. To God the Son also, in denying his Godhead, and counting the blood of the Covenant, wherewith Christ was sanctified by all the Persons of the Godhead, an unholy thing! Joh_10:36; Joh_17:19; Isaiah 61:1; Isaiah 61:1; Matthew 4:1. And to God the Holy Ghost, by whom Christ wrought his miracles, and through whom he offered himself without spot to God, when he made his soul an offering for sin, Hebrews 9:14. And what a trembling scripture follows! Vengeance belongeth unto me! Here needs no comments. It is indeed a fearful thing to fall into the hands of the living God!
