Musar על במדבר 12:7

We learn from this that if even a Moses, of whom G–d Himself had testified that "he is trusted in My entire House" (Numbers 12,7), felt it incumbent to render an account to the people, no Jewish trustee, however well reputed, should feel it below his dignity to offer an accounting of how he spent the public funds entrusted to him.

The second is from Moses, our teacher, peace be upon him. He was the choicest of the creations of the Creator. We know that his excellence was honored in his life, and so was it in his death. We know that his soul had a superiority over other souls and certainly did not perish, and just as in his lifetime he ascended to Heaven, and the Creator, blessed be He, showed him his mysteries, as it is said (Numbers 12:7), “He is trusted in my house,” so does our reason compel us to believe that his soul was not lost in his death. For if his soul were lost, what superiority did it have over others? Since the Lord spoke with him, we know that the power of God’s speaking with him left in him an advantage after his soul had separated from his body, an advantage from which there could be inferred the difference between it and the souls of other creatures with whom God did not speak. If this is so, then this is its good reward. Just as at his death, his soul ascended to the academy on high and did not perish, so will the souls of the righteous rejoice, each according to his service to God and his righteousness.

And concerning Moses, it is written : "In all my house he is faithful" (Num. 12:7). And it is said in the Midrash : "Great is faith before the Holy One, Blessed is He, for because of the merit of the faith that our fathers believed there dwelt upon them the Holy Spirit and they uttered song as it is said : 'And they believed in the Lord and in Moses His servent. Then Moses and the Children of Israel sang' " (Exod. 14:31, 15:1, Exodus Rabbah 22-23).
