Exodus 29:27

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.

Exodus 29:22

29:22 “You are to take from the ram the fat, the fat tail, the fat that covers the entrails, the lobe ²  of the liver, the two kidneys and the fat that is on them, and the right thigh – for it is the ram for consecration ³  –

[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.

[29:22]  ² tn S. R. Driver suggests that this is the appendix or an appendix, both here and in v. 13 (Exodus, 320). “The surplus, the appendage of liver, found with cow, sheep, or goat, but not with humans: Lobus caudatus” (HALOT 453 s.v. יֹתֶרֶת).

[29:22]  ³ tn Heb “filling.”
