Hebrews 9:11-15

But when Messiah appeared as Kohen Gadol of the good things that have now come, passing through the greater and more perfect Tent not made with hands (that is to say not of this creation), He entered into the Holies once for all—not by the blood of goats and calves but by His own blood, having obtained eternal redemption. For 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, how 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? For 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.
