Exodus 29:27-29

Revised Standard Version

²⁷ And you shall consecrate the breast of the wave offering, and the thigh of the priests’ portion, which is waved, and which is offered from the ram of ordination, since it is for Aaron and for his sons. 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.
