Exodus 29:27-29

New Revised Standard Version, Anglicised 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.
