Exodus 29:27-29

Amplified Bible

²⁷ You shall consecrate the waved breast offering [of the ram] used in the ordination and the waved thigh offering of the priests’ portion, since it is [a contribution] for Aaron and for his sons. ²⁸ It shall be for Aaron and his sons as their due portion from the Israelites forever, for it is a ^[a]heave offering. It shall be a heave offering to the Lord from the Israelites from the sacrifices of their peace offerings.

²⁹ “The holy garments of Aaron shall be for his sons after him, to be anointed and ordained in them.
