Hebrews 9:13-14

The blood of goats and bulls and the ashes of a burnt calf are sprinkled on the people who are ritually unclean, and this purifies them by taking away their ritual impurity. Since this is true, how much more is accomplished by the blood of Christ! Through the eternal Spirit he offered himself as a perfect sacrifice to God. His blood will purify our consciences from useless rituals, so that we may serve the living God.
