Hebrews 10:28-31

28Someone who rejected the law of Moses was put to death without mercy on the testimony of two or three witnesses.

29How much greater punishment do you think that person deserves who has contempt for the Son of God, and profanes the blood of the covenant that made him holy, and insults the Spirit of grace?

30For we know the one who said, “Vengeance is mine, I will repay,” and again, “The Lord will judge his people.”

31It is a terrifying thing to fall into the hands of the living God.
