Hebrews 9:12-14

12and he entered once for all into the most holy place not by the blood of goats and calves but by his own blood, and so he himself secured eternal redemption.

13For 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,

14how 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.
