Hebrews 10:2-4

Amplified Bible

² For if it were otherwise, would not these sacrifices have stopped being offered? For the worshipers, having once [for all time] been cleansed, would no longer have a consciousness of sin. ³ But [as it is] these [continual] sacrifices bring a fresh reminder of sins [to be atoned for] year after year, ⁴ for it is impossible for the blood of bulls and goats to take away sins.
