Hebrews 9:12-15

MLV(i) 12 nor through the blood of male-goats and calves, but through his own blood, entered in once for all into the holy of holies, having found everlasting redemption. 13 For if the blood of male-goats and oxen and the ashes of a heifer, sprinkling those who have been desecrated, makes one holy toward the cleanness of the flesh; 14 how much more the blood of Christ, (who through the everlasting Spirit offered himself unblemished to God), will be cleansing your conscience from dead works, that you may give-divine service to the living God.
15 And because of this, he is the intermediary of a new covenant, that his death having happened for the redemption of the transgressions that were against the first covenant, that those who have been called may receive the promise of the everlasting inheritance.
