What will be the consequence of Hashem putting His hand on you?
Malbim: Also after the Churban 1 , you will not find rest among the Goyim.
It seems that here, 'Churban' is the destruction of Amon. (PF)
It is written l'Vag, and we pronounce it l'Vaz!
Radak: The Kesiv is food, like "Pas Bag" (Daniel 1:5). It is like the pronunciation (disgrace), for the food is a Mashal for disgrace. Gimel switches with Zayin according to At-Bach (we exchange Aleph with Tes, Beis with Ches...)
Why does it mention "Goyim" and "Amim"?
Malbim: Goyim are lower. They have no king. Amim are more esteemed; they have a king. You will dwell among the less esteemed Goyim; they will consume you with the entire mouth. I cut you off from the more esteemed Amim. You cannot dwell among them at all.
Why does it say "v'Ha'avadticha"?
Malbim: If you will want to settle in lands by yourself, you will perish from settlement. I will totally destroy you, and you will know "Ki Ani Hashem"!
