What is the significance of the fact that the Torah repeats by every item "Ka'asher Tzivah Hashem es Moshe"?
Ba'al ha'Turim #1 and Moshav Zekenim (on Pasuk 32): Since Moshe requested that Hashem erase him from the Seifer Torah, Hashem responded by repeating his name over and over again. 1
Ba'al ha'Turim #2: Corresponding to the eighteen times that the Torah writes here "Ka'asher (or ke'Chol asher) Tzivah Hashem es Moshe", Chazal instituted the eighteen B'rachos of the Amidah - adding Birkas ha'Minim ('ve'la'Malshinim') corresponding to the one time it writes "ka'Asher Tzivah Hashem Kein Asu". 2
Refer to 39:1:2:1.
Initially, Hashem accepted his request (Refer to 27:20:1:1), and made up for it here. In any event, this is a classical example of the Chazal 'Whoever runs away from Kavod, Kavod runs after him'.
Ba'al ha'Turim: In similar vein, the Gematriya of all the nineteen phrases in question - a hundred and thirteen, is equivalent to the Gematriya of all the conclusions of the B'rachos - 'Baruch Atah Hashem, MageinAvraham", 'Baruch Atah Hashem, Mechayeh ha'Meisim' ... and the hundred and thirteen words that they comprise is equivalent to the number of times the word "Leiv" is mentioned in the Torah.
