Exodus 29:26-28

Amplified Bible

²⁶ “Then you shall take the breast of the ram of Aaron’s ordination, and wave it as a wave offering before the Lord; and it shall be your (Moses) portion. 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.
