What is "Yegi'a Egypt u'Schar Kush"?
Rashi: I informed you how I will save My children from Bavel. This is why I aroused Koresh! I will inform you also of the salvation from Sancheriv in the days of Chizkiyah. He will return to Yerushalayim from (after defeating) Tirhakah Melech Kush. He will come to Yerushalayim with all the coveted treasuries of Kush and Egypt, who will go to help Kush. He will come with the booty and fall in Yerushalayim. Chizkiyah and his nation will take all the spoils. So it says in Seder Olam 23, that this refers to Sancheriv.
Radak: Refer to 19:18:1:1*, 37:7:4:2 and the notes there.
Malbim: Yegi'a Egypt is their money. Sechar Kush is their merchandise.
What are "[Seva'im] Anshei Midah"?

Why will they bow and pray to You?
Radak: They will pray to You to release them from their fetters.

What is the meaning of "Ach Bach Kel"?
Rashi: They will admit that there is no god other than Hashem (Radak - i.e. Elokei Yisrael).

Why does it say "Efes Elokim"?
Malbim: There is no other G-d, for the gods of the Nochrim are nothing.
