29-34. He that offereth the sacrifice of his peace offerings unto the Lord—In order to show that the sacrifice was voluntary, the offerer was required to bring it with his own hands to the priest. The breast having been waved to and fro in a solemn manner as devoted to God, was given to the priests; it was assigned to the use of their order generally, but the right shoulder was the perquisite of the officiating priest.

     35-38. This is the portion of the anointing of Aaron—These verses contain a general summing up of the laws which regulate the privileges and duties of the priests. The word "anointing" is often used as synonymous with "office" or "dignity." So that the "portion of the anointing of Aaron" probably means the provision made for the maintenance of the high priest and the numerous body of functionaries which composed the sacerdotal order.
