Rashi on Deuteronomy 34:7/רש"י על דברים ל״ד:ז׳

1לא כהתה עינו HIS EYE WAS NOT DIM — even after he had died (Sifrei Devarim 357:34).

2ולא נס לחו means, nor did the life-sap that was in him depart (Sifrei Devarim 357:35): decomposition had no power over him (had no effect on his body), and the appearance of his face had not changed.
