Exodus 29:32-33

29:32 Aaron and his sons are to eat the meat of the ram and the bread that was in the basket at the entrance of the tent of meeting. 29:33 They are to eat those things by which atonement was made to consecrate and to set them apart, but no one else may eat them, for they are holy.

tn The clause is a relative clause modifying “those things,” the direct object of the verb “eat.” The relative clause has a resumptive pronoun: “which atonement was made by them” becomes “by which atonement was made.” The verb is a Pual perfect of כִּפֵּר (kipper, “to expiate, atone, pacify”).

tn The Hebrew word is “stranger, alien” (זָר, zar). But in this context it means anyone who is not a priest (see S. R. Driver, Exodus, 324).
