Radak: Just like there is no Elokim like You, there is no nation like Your nation Yisrael.

Who are the Elokim that redeemed Yisrael?
Rashi, from Midrash Shmuel 27:3: They are Moshe and Aharon 1 - "Nesaticha Elokim l'Pharaoh" (Shemos 7:1). Also Yonason translates 'messengers from Hashem.'
Radak: It is Hashem. 2 The plural is used for honor, like "Yismach Yisrael b'Osav" (Tehilim 149:2). In Divrei ha'Yamim I, 17:21, it says "Asher Halach Elokim" (singular).

What is the meaning of "Goyim vEi'lohav"?
Radak #1: [You redeemed them] from nations and from their gods. The prefix Mem in "mi'Mitzrayim" applies also to Goyim and to Elohav.
Radak #2: You struck nations and their gods, like "uv'Chol Elohei Mitzrayim E'eseh Shefatim" (Shemos 12:12).
Radak #3: They are Yisrael and their Chachamim and great people. It is plural, for there are families in Yisrael, e.g. "Binyamin b'Amemecha" (Shoftim 5:14). VEilohav is like "Elokim Lo Sekalel" (Shemos 22:27), i.e. judges.
