Who are "Mogayich"?
Rashi: They are those who move and relocate you, like "he'Hamon Namug" (Shmuel I, 14:16).
Radak: The root is Yageh (grieve) like "Hashem Hogah" (Eichah 1:5).
Malbim: They are Nochrim, who Hogu (grieved), pained and Magegu (melted) you. Giving the cup to them corresponds to "vEi'lokayich Yariv Amo" (22).
Why did they say "Shechi v'Na'avorah"?
Rashi: Bend down, and we will pass over your back.
Malbim: The Nochrim in India wanted to give to Yisrael bodily freedom 1 if they will bend their Nefesh and Neshamah (subjugate them) to idolatry. You chose bodily affliction over affliction of the Nefesh.
I.e. they will pass over (exempt) them. We corrected the text of Malbim to say 'Cherus'. (PF)
Why does it say "Nafshech" and "Gavech"?
Radak: The Nefesh is afflicted via afflictions of the body.
Why does it say "va'Tasimi [cha'Aretz Gavech]"?
Radak: You suffered all this due to love of Me.
Malbim: You made your back like the ground - anyone who wants can pass on it.
Where is "vecha'Chutz"?
Radak: Like in the market, where everyone passes over it.
