'Blood of the Covenant' in the Bible

Moses took the blood, and sprinkled it on the people, and said, "Look, this is the blood of the covenant, which the LORD has made with you concerning all these words."

for this is my blood of the covenant, which is poured out for many for the remission of sins.

saying, "This is the blood of the covenant which God has commanded you."

How much worse punishment, do you think, will he 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?
