Hebrews 9:15-10:18 NASB
1 For the Law, since it has only a shadow of the good things to come and not the very form of things, can never, by the same sacrifices which they offer continually year by year, make perfect those who draw near. 2 Otherwise, would they not have ceased to be offered, because the worshipers, having once been cleansed, would no longer have had consciousness of sins? 3 But in those sacrifices there is a reminder of sins year by year. 4 For it is impossible for the blood of bulls and goats to take away sins.
