Moses, who lost out on permission to enter the land, pleaded one last time with H’Shem. He did not expect to change the L-RD’s mind, based upon any merit that he might claim for himself; for, it was precisely his demerit, having struck the rock, instead of speaking to the rock, that compelled G-d to decree that neither Moses, nor Aaron would enter the Land. Yet, try and try again, for the sake of making an appeal to the L-RD, Who on several occasions in the past, relented from strict judgment against Israel.
To no avail, Moshe’s pleas only brought the retort that the L-RD had heard enough, he would not change his mind. Why, we may ask, when Moses acted on behalf of the people, the L-RD forgave them, and lessened the judgment; yet, in asking for himself, he is refused? Although I am not prone to speculation, one answer could be because of the high level of expectations the L-RD had of him, as well as Aaron, because of their leadership positions. For, more is expected of those who have greater responsibilities to others.
Yet, consider, that all was not lost upon Moses, for his error; rather, as Rashi comments, his consolation prize, so to speak, was permission to enter Olam Haba (the World to Come). And, this, in all estimation, is really the greater reward – one that we should also look forward to in great expectation. For, this world is like a corridor, where we prove ourselves to the L-RD, so that we may enter the banquet hall, symbolic of the World to Come (Pirkei Avos 4:21). Like Moshe, regardless of whatever unfulfilled dreams we may have in our own lives, G-d will grant an even greater reward to us, if we remain faithful to Him.
