Exodus 29:28-30

Revised Standard Version

²⁸ It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is the priests’ portion to be offered by the people of Israel from their peace offerings; it is their offering to the Lord.

²⁹ “The holy garments of Aaron shall be for his sons after him, to be anointed in them and ordained in them. ³⁰ The son who is priest in his place shall wear them seven days, when he comes into the tent of meeting to minister in the holy place.
