Hebrews 9:13-14

Revised Standard Version Catholic Edition

¹³ For if the sprinkling of defiled persons with the blood of goats and bulls and with the ashes of a heifer sanctifies for the purification of the flesh, ¹⁴ how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify your^[a] conscience from dead works to serve the living God.
