Moshe Rabbeinu, the eternal leader, tried his hardest to get us to our Final Redemption as fast as he could. If he had walked any faster he probably would have left us behind, for the nation was not as eager to follow in the Ways of G-d wholeheartedly. He wanted to use the Land as a passageway, E'ebra, but Hashem used him as a passageway, His'aber bi, and insisted the shepherd stay with his flock in the wilderness.
On a deeper level though, we must understand this word His'aber, which literally means to become pregnant. Simply speaking its a metaphor for Hashem becoming full of anger, but on a more profound level it means that Hashem spiritually impregnated Moshe with so much wisdom that he was nearly bursting. Although the Sin of the Golden Calf caused him to lose the fiftieth and ultimate level of understanding, it was returned to him at that point (ba'es hahee) before his death so as to see the Holy Land and infuse it with that holiness. His destiny was not to enter the land himself, only to facilitate the entrance of his people, lema'anchem, for you. The Ariz"l taught that Moshe Rabbeinu is continually reborn throughout the generations as the Torah leader of the period who guides them in their persistent endeavor to enter the Holy Land as he himself wished: as a passageway to eternal perfection. To this purpose he now started chiding the people: "You, who saw all the miracles — forget not the Ten Commandments you heard from G-d; teach your children what you saw and heard. Hear O Israel — Do you still hear it? Hashem is speaking to us constantly if we just listen carefully."
Let us not become stale in our efforts to attain the sublime: it calls out and beckons us to strive harder, to become eternal, to live with G-d.
