Hebrews 9:14; Hebrews 9:22

14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!

22 In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.
