Hebrews 9:22-23

9:22 Indeed according to the law almost everything was purified with blood, and without the shedding of blood there is no forgiveness. 9:23 So it was necessary for the sketches of the things in heaven to be purified with these sacrifices, but the heavenly things themselves required better sacrifices than these.

Hebrews 10:2

10:2 For otherwise would they not have ceased to be offered, since the worshipers would have been purified once for all and so have no further consciousness of sin?
