The Question

1. Rashi’s point is that the trumpets “were hidden away [by God] even during his [Moshe’s] lifetime, prior to the day of his passing, thus affirming the words of the verse, ‘and there is no ruling on the day of death.’ What does Yehoshua’s access to the trumpets have to do with this explanation?
2. Why does Rashi cite the words ‘to me’ in the introduction to his comment?

Seemingly, Rashi is focusing on how Moshe’s directive to “assemble” was accomplished without trumpets. How does the rest of Moshe’s directive, “to me,” figure in Rashi’s commentary?
