Charles Ellicott Commentary Leviticus 7:35

"This is the anointing-portion of Aaron, and the anointing-portion of his sons, out of the offerings of Jehovah made by fire, in the day when he presented them to minister unto Jehovah in the priest`s office;" — Leviticus 7:35 (ASV)

This is the portion of the anointing of Aaron and of the anointing of his sons. —Better, this is the share of Aaron and the share of his sons. That is, the wave breast and the heave shoulder.
