Hebrews 10 - 5+ "When Jesus was about to come into the world, he said to God:
"you do not want sacrifices and offerings,
but you have prepared a body for me.
You are not pleased with animals burnt whole on the altar
or with sacrifices to take away sins.
Then I said here I am
to do your will, O God
just as it is written in the book of the Law.
First he said "you neither want not are you pleased with sacrifices and offerings or with animals burnt on the altar and the sacrifies to take away sins. He said this even though all these sacrifices are offered acdording to the Law. Then he sad "Here I am, O God, to do your will" So God does away with all the old sacrifices and puts the sacrifice of Christ in their place. Because Jesus Christ did what God wanted him to do, we are all purified from sin by the offering that he made of his own body once and for all.

Every Jewish priest performs his services every day and offers the same sacrifices many times: but these sacrifices can never take away sins. Christ, however, offered one sacrifice for sins, an offering that is effective forever."

15 - "This is the covenant that I will make with them in the days to come, says the Lord. I wil put my laws in their hearts and write them in their minds. And then he says "I will remember their sins and evil deeds no more." So, when these have been forgiven, an offering to take away sins is no longer needed. We have then, my brothers, complete freedom to go into the Most Holy Place by means of the death of Jesus. He opened for us a new way, a living way, through the curtain - that is his own body."
