When Moses asked around and learned that the ram for the sin sacrifice had already been burned on the altar, he became angry with Eleazar and Ithamar and said,
how the priests from Aaron's family were to offer the sacrifice for sin: This sacrifice is very sacred, and the animal must be killed in my presence at the north side of the bronze altar.
The ceremony for this sacrifice and the one for sin are just alike, and the meat may be eaten only by the priest who performs this ceremony of forgiveness.
