Hebrews 10:1-4

WPNT(i) 1 You see, the Law is but a shadow of the good things to come, not their actual matter, so it can never perfect those who approach with the same sacrifices that they offer endlessly, year after year. 2 Otherwise would they not have ceased to be offered, since the worshippers would have had no more consciousness of sins, having been cleansed once for all? 3 However, those sacrifices are an annual reminder of sins, 4 because it is impossible for the blood of bulls and goats to take away sins.
