And he said unto me,
Unto two thousand and three hundred days;
then shall the sanctuary be cleansed.
Daniel 8:14
Q: What was Cleansed?
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.
Hebrews 9:22,23
A: The cleansing is with blood--hence it is a cleansing from sin.
