Exodus 29:29-31

Authorized (King James) Version

²⁹ And the holy garments of Aaron shall be his sons’ after him, to be anointed therein, and to be consecrated in them. ³⁰ And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place.

³¹ And thou shalt take the ram of the consecration, and seethe his flesh in the holy place.
