Yom Kippur Reenactment
A reenactment of Yom Kippur (the day of atonement) the most holy day in the Jewish year. On this day the High Priest entered the Holy place and sprinkled blood from the sacrifice on the mercy seat of the ark of the covenant.
Only the High Priest could enter this room, and only blood can cover sin “…it is the blood that makes atonement for the soul” Leviticus 17:11. And the High Priest could only enter this room one day a year, Yom Kippur.
