What are the connotations of "Re'u Atah ki Ani Ani Hu ve'Ein Elokim Imadi ... !"
Rashi (on Pasuk 43, according to R. Nechemyah): Then Hakadosh-Baruch-Hu will reveal His salvation and declare (to the nations) - 'See now that I am He; from Me there emerged the evil (on Yisrael) and from Me will come the salvation! ... and there is no-one who will save you from the evil that I will bring upon you!'
Ramban: Refer to 32:38:2:1*. In order to counter that, Hashem announces that He is alone and there is no god with Him to assist Him; nor is there anyone to save from His Hand or to prevent Him from doing as He wishes. 1
Rashbam: 'It is in answer to the enemy's question 2 'Where is your G-d ...?'
Seforno: 'See now that I am the One who punished Yisrael - it was not the work of the celestial ministers or the hosts of the Heaven'.

Riva: The enemy said "Yakumu v'Ya'azruchem" (plural). Know that I am alone!

Why does Hashem repeat the word "Ani"?
Rashi: 'I bring down and I raise'.
Ibn Ezra: To teach us that He is the same G-d who killed Yisrael and He is the One who will bring them back to life. 1
Riva citing R"M of Kutzi: The first Ani refers to "I killed, and I will return to life." The second refers to "I smote, and I will heal."
What are the implications of "Ani Amis Va'achayeh, Machatzti va'Ani Erpa"?
Ramban: No one can stop Me from doing what I want - to kill or return to life, to wound or to heal!'
Targum Yonasan: 'I smote My nation and I will heal them at the end of days and there is nobody to save Gog and his camp from My Hand when he comes to fight with Yisrael!' 5
Hadar Zekenim: If I killed [Yisrael], I will bring them back to life. If I smote [Yisrael], I will heal them. However, you (the other nations)
