Rashi on Deuteronomy 3:26/רש"י על דברים ג׳:כ״ו

1ויתעבר ה׳ This means, GOD WAS FILLED WITH WRATH (Sifrei Bamidbar 135).

2למענכם ON ACCOUNT OF YOU — You caused this for me (that God was wroth with me); similarly it states, (Psalms 106:32) “And they provoked Him at the waters of Meriba, and He did evil to Moses on their account".

3רב לך LET IT SUFFICE THEE (i.e. pray no more), so that people should not say, “How harsh is the Master, and how obstinate and importunate is the disciple" (Sotah 13b). Another explanation of רב לך (lit., there is much for you) — more than this is reserved for you; much is the goodness that is stored up for thee (Sifrei Bamidbar 135).
