Hebrews 9:13-17

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 Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?

For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the violations that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.

For where there is a covenant, there must of necessity be the death of the one who made it.

For a covenant is valid only when people are dead, for it is never in force while the one who made it lives.
