The Yom Kippur Sacrifices

If sin could be expiated simply by laying it on the living goat and driving it away into the desert, then obviously the whole ceremonial sacrificial system would be pointless. Rather, a sacrificial death is necessary. As it says in Leviticus 1711, for the life of the flesh is in the blood, and I have given it for you upon the altar to make atonement for your sins,. For it is the blood that makes atonement by reason of the life.
