Hebrews 9:18 (KJV)

For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:

How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.

For where a testament is, there must also of necessity be the death of the testator.

For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.

For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people,

Saying, This is the blood of the testament which God hath enjoined unto you.

Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry.

And almost all things are by the law purged with blood; and without shedding of blood is no remission.

It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
