Exodus 29:28-30

American Standard Version

²⁸ and it shall be for Aaron and his sons as their portion for ever from the children of Israel; for it is a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifices of their peace-offerings, even their heave-offering unto Jehovah.

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