Hebrews 10:29-31

Darby Translation

²⁹ of how much worse punishment, think ye, shall he be judged worthy who has trodden under foot the Son of God, and esteemed the blood of the covenant, whereby he has been sanctified, common, and has insulted the Spirit of grace?

³⁰ For we know him that said, To me [belongs] vengeance; *I* will recompense, saith the Lord: and again, The Lord shall judge his people.

³¹ [It is] a fearful thing falling into [the] hands of [the] living God.
