The LORD spoke to Moses after the death of the two sons of Aaron, when they came near before the LORD, and died; and the LORD said to Moses, “Tell Aaron your brother not to come at just any time into the Most Holy Place within the veil, before the mercy seat which is on the ark; lest he die; for I will appear in the cloud on the mercy seat.
“Aaron shall come into the sanctuary with a young bull for a sin offering, and a ram for a burnt offering.
