The table below presents two contradictory verses/verselets. Both verses/verselets speak about the requirement to wash hands and legs from the Temple Lavere. The underlined words highlight the contradiction. One verse/verselet says Aaron and his sons washed while the other verse/verselet says Moses, Aaron and his sons washed. We see the contradiction: Which is it? Was the washing a requirement only of Priests; or did Moses also participate. Rashi simply resolves this using the 2 aspects method: a) During the Priest induction ceremony, Moses performed sacrificial rituals; hence he had to wash from the Temple Lavere. The Priest induction ceremony is described in Lv08-16:21. We find there that indeed, Moses functioned as a Priest (because there were not yet other Priests); he offered sacrifices, sprinkled blood etc. Hence as just indicated he was required to wash from the Temple Lavere. b) After the Priests were inducted, Moses remained a Levite and was never required to wash from the Lavere again.
