New Living Translation
28 For anyone who refused to obey the law of Moses was put to death without mercy on the testimony of two or three witnesses. 29 Just think how much worse the punishment will be for those who have trampled on the Son of God, and have treated the blood of the covenant, which made us holy, as if it were common and unholy, and have insulted and disdained the Holy Spirit who brings God’s mercy to us. 30 For we know the one who said,
“I will take revenge.
I will pay them back.”[a]
He also said,
“The Lord will judge his own people.”[b]
