In Leviticus chapter 16 we see the Old Testament Symbolism for the Day of Atonement and its part of the plan of salvation as God explains the meaning of it to ancient Israel. In Leviticus 16: it says, Aaron the high priest was to select 2 goats, one that represented Jesus Christ and the other goat… satan the devil. We understand the goat that represented Jesus would be the one to be slain as a representation of His sacrifice for all mankind and the other representing satan. This goat would be sent away from the children of Israel picturing satan being bound and chained for a thousand years.
