Exodus 29:25-28
English Standard Version
26"You shall take the breast of the ram of Aaron 's ordination and wave it for a wave offering before the Lord, and it shall be your portion.
27And you shall consecrate the breast of the wave offering that is waved and the thigh of the priests ' portion that is contributed from the ram of ordination, from what was Aaron 's and his sons '.
28It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is a contribution. It shall be a contribution from the people of Israel from their peace offerings, their contribution to the Lord.
