The bull and the goat for the sin offerings must be taken outside the camp. Their blood was brought into the Most Holy Room. It paid for sin. The hides, meat and guts of the animals must be burned up.
The rest of the grain offering belongs to Aaron and the priests in his family line. It is a very holy part of the food offerings presented to the Lord.
In other words, all the rest of the bull must be taken away. The priest must take it outside the camp. He must take it to a “clean” place. He must take it to the place where the ashes are thrown. Then he must burn it there in a wood fire on a pile of ashes.
The son of Aaron who will become the next high priest after him will prepare the grain offering. It is the share that must be given to the Lord for all time to come. It must be completely burned up.
