Our Parsha notes:
“And Aaron did so, toward the face of the Menorah he kindled the lamps, as Hashem had commanded Moshe.” (Sefer Bamidbar, Perek 8, posuk 3 translation as rendered in the Artscroll Chumash, page 775)
Many commentators including Rashi and the S’fas Emes, as cited by by R’ Zelig Pliskin in “Growth Through Torah”, note that this posuk expresses the epitomization of the enthusiasm and constancy of Aaron HaKohen’s Service in the Mishkan as a paradigm for B’nai Yisrael to emulate.
