Keluaran 29:27-28

29:27 You are to sanctify the breast of the wave offering and the thigh of the contribution, ¹  which were waved and lifted up as a contribution from the ram of consecration, from what belongs to Aaron and to his sons. 29:28 It is to belong to Aaron and to his sons from the Israelites, by a perpetual ordinance, for it is a contribution. It is to be a contribution from the Israelites from their peace offerings, their contribution to the Lord.

[29:27]  ¹ sn These are the two special priestly offerings: the wave offering (from the verb “to wave”) and the “presentation offering” (older English: heave offering; from a verb “to be high,” in Hiphil meaning “to lift up,” an item separated from the offering, a contribution). The two are then clarified with two corresponding relative clauses containing two Hophals: “which was waved and which was presented.” In making sacrifices, the breast and the thigh belong to the priests.
