“...and Moshe became angry with Elazar and Itamar...And Aaron spoke to Moshe, "But today, did they offer up...” Moshe heard [this], and it pleased him” (Vayikra 10-20). [Moshe] admitted [that Aaron was correct,] and was not ashamed, [for he could have covered up by] saying, “I have not heard [of this law. Rather, Moses said to Aaron, “You are right! I did hear that an אוֹנֵן must not eat from sacrifices that will be offered in future generations, but I forgot!”]. -- Rashi to Vayikra 10:20 (additions in brackets are based on Zevachim 101b and Toras Kohanim 10:60)
