Exodus 29:29-31

Amplified Bible, Classic Edition

²⁹ The holy garments of Aaron shall pass to his descendants who succeed him, to be anointed in them and to be consecrated and ordained in them.

³⁰ And that son who is [high] priest in his stead shall put them on [each day for] seven days when he comes into the Tent of Meeting to minister in the Holy Place.

³¹ You shall take the ram of the consecration and ordination and boil its flesh in a holy and set-apart place.
