Musar sobre Levítico 8:6

At the end of פרשת צו the Torah mentions the sanctity of Aaron and his sons and how they were sanctified. The Torah (8,6) writes there: ויקרב משה את אהרון ואת בניו, "Moses offered Aaron and his sons (as a sacrifice)." The Torah had also commanded Moses to do just that in Exodus 28,1. The meaning of these verses is that Aaron as well as his sons themselves served as sacrifices, i.e. the mystical dimension of אדם, as we have explained this at the very beginning of the Book of Leviticus.
