Hebrews 10:3-13 RSV

3 But in these sacrifices there is a reminder of sin year after year.
4 For it is impossible that the blood of bulls and goats should take away sins.
5 Consequently, when Christ came into the world, he said, "Sacrifices and offerings thou hast not desired, but a body hast thou prepared for me;
6 in burnt offerings and sin offerings thou hast taken no pleasure.
7 Then I said, 'Lo, I have come to do thy will, O God,' as it is written of me in the roll of the book."
8 When he said above, "Thou hast neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings" (these are offered according to the law),
9 then he added, "Lo, I have come to do thy will." He abolishes the first in order to establish the second.
10 And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.
11 And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins.
12 But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God,
13 then to wait until his enemies should be made a stool for his feet.
