Why does it say "Zichru Toras Moshe Avdi"?
1.
Mahari Kara: From now and onwards you will not have Nevi'im rebuking you. Mal'achi was the last prophet. Remember Toras Moshe, and this will bring the Ge'ulah close!
2.
Radak: Until the day of judgment comes, every generation must remember Toras Moshe, to do like all that is written in it.
3.
Malbim: This is the last Nevu'ah until the Ketz. Do not hope for more Nevu'ah. Remember Torah - it teaches you what to do!
2)
What do we learn from "Asher Tzivisi Oso v'Chorev"?
1.
Radak: This refutes those who say that the Torah was given afterwards.
