Hebrews 9:10

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 9:13-14

9:13 For if the blood of goats and bulls and the ashes of a young cow sprinkled on those who are defiled consecrated them and provided ritual purity, 9:14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our consciences from dead works to worship the living God.
