John Gill Commentary Leviticus 8:31

"And Moses said unto Aaron and to his sons, Boil the flesh at the door of the tent of meeting: and there eat it and the bread that is in the basket of consecration, as I commanded, saying, Aaron and his sons shall eat it." — Leviticus 8:31 (ASV)

And Moses said to Aaron, and to his sons
After he had offered the bullock, the two rams, and cakes of unleavened bread for the consecration of them:

boil the flesh at the door of the tabernacle of the congregation ;
the remainder of the flesh of the ram of consecration, which was all but the fat, the shoulder, and the breast:

and there eat it with the bread that is in the basket of
consecration ;
what was left of that, there being one cake of a sort taken out of it and burnt:

as I commanded, saying, Aaron and his sons shall eat it ;
see (Exodus 29:32) .
