'Blood of the Covenant' in the Bible

So Moses took the blood and sprinkled it on the people, and said, “Behold the blood of the covenant, which the Lord has made with you in accordance with all these words.”

for this is My blood of the covenant, which is poured out for many for forgiveness of sins.

And He said to them, “This is My blood of the covenant, which is poured out for many.

saying, “This is the blood of the covenant which God commanded you.”

How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
