By Dave Armstrong, National Catholic Register - In the Old Testament sacrificial system, there was a difference between the sacrifice itself and the offering of the sacrifice to God... The Bible describes the procedure that took place on the Day of Atonement (Yom Kippur), in Leviticus 16:11-16. First, the sacrifice was made by the high priest, and then blood was taken from it (both from a bull and a goat) into the Holy of Holies (the holiest part — the inner sanctum — of the Temple, and the Tabernacle, before the Temple) and sprinkled onto the mercy seat between the two cherubim, which was above the ark of the covenant, where God was specially present (Exodus 30:6).
