(3:25) Please let me cross the Jordan. Let me see the good land across the Jordan, this good mountain, and the Lebanon.
Please let me cross the Jordan R. Simla'i expounded: Why did Moses our teacher desire to enter the Land of Israel? Did he want to eat of its fruits or be satiated with its goodness? Certainly not. But this is what Moses said: The Jews were given many commandments that can only be fulfilled in the Land of Israel. I want to enter the Land of Israel so that I should be able to fulfill all of them (Sotah 14a).
(3:26) But God was angry with me because of you, and He would not listen to me. God said to me, “Enough! Do not speak to Me any more about this!”
Enough! R. Levi said: Moses used the term Enough! in addressing the rebellious Korach and his party, saying, “Enough! you sons of Levi!” (Numbers 16:7). And with the same Enough!, he was addressed when God said to him, “Enough! Do not speak to Me any more about this!” God used Moses' own phrase, indicating that His decision was final (Sotah 13b).
