Hebrews 9:9-10

9:9 This was a symbol for the time then present, when gifts and sacrifices were offered that could not perfect the conscience of the worshiper. 9:10 They served only for matters of food and drink and various washings; they are external regulations imposed until the new order came.

Hebrews 9:23

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.
