Hebrews 9:23-26

It was necessary therefore that the copies of the things in the heavens should be cleansed with these; but the heavenly things themselves with better sacrifices than these. For Christ entered not into a holy place made with hands, like in pattern to the true; but into heaven itself, now to appear before the face of God for us: nor yet that he should offer himself often, as the high priest entereth into the holy place year by year with blood not his own; else must he often have suffered since the foundation of the world: but now once at the end of the ages hath he been manifested to put away sin by the sacrifice of himself.
