R’ Moshe Feinstein asks, Why the double Lashon? Why does it say both ??-???? ???, ???? ????? (I cannot go or come) and ????-? ??? ???, ?? ???? ??-????? ??? (And Hashem told me I cannot cross the Jordan).
R’ Moshe says that Moshe Rabbeinu is giving Klal Yisroel an important mussar. A person has bechira, free choice. Moshe too could have chosen to go against Hashem’s will and tried to enter Eretz Yisroel.
When something is forbidden to us, we must view it as “we are incapable of doing it”. This is what Moshe Rabbeinu is teaching us here. Our game plan for battle against our yetzer hara should not be “I’m going to chose the other way” but rather we should view that which is assur as something which is impossible for us to do, just like Moshe did here.
