Wikisource — Sifra on Vayikra 9:21
English: Aaron waved the breast and the right thigh as a wave offering, demonstrating how Aaron and his sons learned the sacrificial service.
Functional analogy — The source interprets the verse through its wording and context.
Sifra uses the waving of the breast and right thigh to emphasize the exceptional achievement of Aharon and his sons: in a short time they mastered seven sacrificial services.
