Hebrews 10:5-10, 29

That is why, when Christ came into the world, he said to God, “You did not want animal sacrifices or sin offerings. But you have given me a body to offer. You were not pleased with burnt offerings or other offerings for sin. Then I said, ‘Look, I have come to do your will, O God— as is written about me in the Scriptures.’” First, Christ said, “You did not want animal sacrifices or sin offerings or burnt offerings or other offerings for sin, nor were you pleased with them” (though they are required by the law of Moses). Then he said, “Look, I have come to do your will.” He cancels the first covenant in order to put the second into effect. For God’s will was for us to be made holy by the sacrifice of the body of Jesus Christ, once for all time.

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.
