Exodus 29:27-29

New Revised Standard Version Catholic Edition

²⁷ You shall consecrate the breast that was raised as an elevation offering and the thigh that was raised as an elevation offering from the ram of ordination, from that which belonged to Aaron and his sons. ²⁸ These things shall be a perpetual ordinance for Aaron and his sons from the Israelites, for this is an offering; and it shall be an offering by the Israelites from their sacrifice of offerings of well-being, their offering to the Lord.

²⁹ The sacred vestments of Aaron shall be passed on to his sons after him; they shall be anointed in them and ordained in them.
