In Response to Death

What is the nature of Aharon’s reaction to the deaths of his sons, and of the exchange between Moshe and Aharon? What is the significance of Aharon’s silence? Through a close examination of the episode we can understand these responses and come to a realization that these deaths may have been necessary in order to teach the nation the proper caution and respect towards God's sanctity.  The connection between "mortals hewn of material substances" and Divine sanctity requires a special Divine service; it involves special rules.  Any deviation from these rules is dangerous, but drawing closer in accordance with the rules is truly part of God's will.  It is this that instills man with power and sanctity, raising him up and completing him.
