Leviticus 16:1-3 English Revised Version (ERV)

1. And the LORD spake unto Moses, after the death of the two sons of Aaron, when they drew near before the LORD, and died;

2. and the LORD 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.
