Question

I heard on Simchat Torah from Rabbi Avigdor Nebenzahl that Moses had a positive commandment of “and die” on the mountain that you are ascending there. And therefore Rashi says that he went up the mountain in a leap, because he was eager to fulfill a positive commandment [ostensibly there were 3: go up, see the land, and die]. [And not because he belittled temporary life and so did not go up slowly, nor in order to show the people his love for the Land of Israel, but only out of eagerness for a positive commandment.] My question: is there no one else in the Hebrew Bible who is commanded to “and die”? And does this explain the midrash that the Angel of Death came to take his soul and Moses rebuked him: I brought down the Torah, and who are you anyway, etc., and this took time — meaning: ostensibly his consent was needed, until he agreed only to the Holy One, blessed be He, Himself, through the death by a divine kiss? And in general, why is there no positive commandment for all human beings to die, from “for dust you are, and to dust you shall return”? And ostensibly this too depends on every person’s consent [in that he accepts death upon himself and submits to the Creator’s decree], as Rashi brings on Psalms, “before Him shall bow all those who go down to the dust,” that all human beings at the time of their death merit a revelation of the Divine Presence and as if bow to their Maker, and only then die… So it seems that there is a process a person must undergo in order to agree to die [and ostensibly this is also what Rabbi Samson Raphael Hirsch says about the severity of corpse-impurity, the “father of fathers of impurity,” because he consented to cessation, to death, and this is the root of impurity and the opposite of life].
