Exodus 29:28-30

New Revised Standard Version, Anglicised Catholic Edition

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. ³⁰ The son who is priest in his place shall wear them for seven days, when he comes into the tent of meeting to minister in the holy place.
