Leviticus 16:2-3
2
and Jehovah said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, before the mercy-seat which is upon the ark; that he die not: for I will appear in the cloud upon the mercy-seat.
3
Herewith shall Aaron come into the holy place: with a young bullock for a sin-offering, and a ram for a burnt-offering.
