Hebrews 9:13-15

13For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh,

14how much more will the blood of Messiah—who through the eternal Spirit offered Himself without blemish to God—cleanse our conscience from dead works to serve the living God?

15For this reason He is the mediator of a new covenant, in order that those called may receive the promised eternal inheritance—since a death has taken place that redeems them from violations under the first covenant.
