29How much worse punishment do you think he will be judged worthy of who has trodden under foot the Son of God, and has counted the blood of the covenant with which he was sanctified an unholy thing, and has insulted the Spirit of grace? 30For we know him who said, “Vengeance belongs to me. I will repay,” says the Lord. Again, “The Lord will judge his people.”
