Hebrews 9:21 (KJV)

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.

Whereupon neither the first testament was dedicated without blood.

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.

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.

For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:

Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;

For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
