Moses devoted his life to three things, and they were (all) called by his name. He devoted his life to Torah and it was called by his name, viz. (Malachi 3:22) "Remember the Torah of Moses, My servant." Now is it not the Torah of G–d? viz. (Psalms 19:8) "The Torah of the L–rd is whole, restoring the soul." How, then, are we to understand "the Torah of Moses, My servant"? Because he devoted his life to it, it is called by his name.
