Hebrews 10:29-31

21st Century King James Version

²⁹ Of how much sorer punishment, suppose ye, shall he be thought worthy who hath trodden under foot the Son of God, and hath accounted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath despised 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.
