It was needful therefore that the copies of the things in Heaven should be cleansed in this way, but that the heavenly things themselves should be cleansed with more costly sacrifices.

For then would not the sacrifices have ceased to be offered, because the consciences of the worshippers--who in that case would now have been cleansed once for all--would no longer be burdened with sins?
