What do we learn from "v'Anochi Hashem Elokecha me'Eretz Egypt"?
Rashi: Therefore you should not have rebelled against Me.
Radak: Refer to 12:10:1:3.
Malbim: They said that Hashem does not supervise them by Himself, and they need an intermediary - "uv'Navi He'elah Hashem Es Yisrael mi'Egypt" (12:4). Therefore they made the calves for an intermediary. The Navi refutes them - I took you out of Egypt without an intermediary.
What do we learn from "vEi'lohim Zulasi Lo Seda"?
Radak: You should not have known to serve gods other than Me, for you see that no one saves, other than Me!
Malbim: When I took you out of Egypt, there was no other god with Me.
Why does it add "u'Moshi'a Ayin Bilti"?
Malbim: I did not send a Shali'ach to save you. I saved you by Myself, without an intermediary!
