Commentaire sur Les Nombres 3:51

ויתן משה את כסף הפדויים, Moses gave the redemption money, etc. Seeing that the verse commences by telling us that Moses had given the redemption money to Aaron and his sons at the command of G'd, why does the Torah repeat: "as G'd had commanded Moses?" Perhaps the reason is that seeing Aaron and his sons had a direct financial benefit from this מצוה we could have assumed that Moses enjoyed the fact that he could bestow this benefit on his brother and nephews. The Torah tells us that Moses had no such considerations and that he performed G'd's instructions solely because he was commanded to do so.
