Hebrews 10:2-6

For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.

But in those sacrifices there is a remembrance again made of sins every year.

For it is not possible that the blood of bulls and of goats should take away sins.

Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:

In burnt offerings and sacrifices for sin thou hast had no pleasure.
