How does one translate "Azi v'Zimras Kah, va'Yhi Li li'Yeshu'ah"?
Rashi #1 (citing Targum Onkelos) and Targum Yonasan: My strength and my praise 1 is the fear of Hashem 2 (which extends over the whole world -Targum Yonasan); He issued the command and it became my salvation.
Rashi #2 and Seforno: The might and vengeance of Hashem was for me a salvation. 3
Ramban (citing Ibn Ezra): My might is Hashem and Hashem is my song (of praise), for He was my salvation. 4
Rashbam: Hashem is the might and the praise of Yisrael; He was for me a salvation.
Ba'al ha'Turim (14:10): Uza, the angel of Egypt, had descended to assist his nation. Hashem opposed him, therefore it says "Azi".
See Rashi's objection (on grammatical grounds) to this explanation.
Because by casting the horse and rider into the sea He revealed His might, that He is King of the world, and that it is therefore befitting for those who were saved to praise Him with song, in their rejoicing to be servants of the King of the world (Seforno).

Hence Chazal said that a maidservant at the Yam-Suf saw more than the prophets (Yechezkel ben Buzi) - with regard to the actual vision, but not as far as the depth of understanding is concerned (See Sifsei Chachamim).
Targum Yonason: With reference to when, in Egypt, their mothers had gone out to the fields, and, after giving birth to them and leaving them there, Hashem had sent an angel to bathe them and dress them.

Rashi (Shabbos 133b): "Ve'anveihu" is like Ani va'Hu. (This is part of a name of Hashem derived from verses 14:19-21 above - Rashi Sukah 45a. Moshe used this name to split the sea, therefore we use it when praying for water on Hoshana Raba - Chizkuni 14:21).
Lev Eliyahu p.75: It does not say to have mercy like Him, rather, to be merciful like Him. (without limit). Also you should be merciful to the extent of your ability! This is like the difference between doing Chesed and loving Chesed.
