16:1 Rashi explains a special warning was given to Aharon not to fall into the trap of his sons. The question is asked does a great person such as Aharon need such a warning? The danger of the issur wasn’t a simple act of taavah but rather a result of deep and even deeper connecting with Hashem where a great person can lose himself over the inspiration and enthusiasm.
Have a great connection to the Shabbos HaGadol and a wonderful Shabbos.
