Why does the Torah repeat by every item "Ka'asher Tzivah Hashem es Moshe"?
Ba'al ha'Turim #1: Since Moshe requested that Hashem erase him from the Sefer Torah, Hashem responded by repeating his name over and over again. 1
Ba'al a'Turim #2: It is corresponding to the eighteen times that the Torah writes here "Ka'asher (or "u'ke'Chol asher) Tzivah Hashem es Moshe" that Chazal instituted the eighteen Berachos of the Amidah - adding Birchas ha'Minim ('ve'la'Malshinim') corresponding to the one time it writes "ka'asher Tzivah Hashem kein Asu". 2
