By his will we have been made holy through the offering of the body of Jesus Christ once for all.

and he entered once for all into the most holy place not by the blood of goats and calves but by his own blood, and so he himself secured eternal redemption.

He has no need to do every day what those priests do, to offer sacrifices first for their own sins and then for the sins of the people, since he did this in offering himself once for all.
