What does the verse teach about the other side of the Kush rivers?
Rashi: From there they will bring to Me a gift. Malbim - not only nations in the middle of civilization - rather, even those on the other side of the Kush rivers [will bring a gift].
Radak: It discusses those who live there. Targum Yonasan says, these are the rivers of Hodu 1 (India).
This is like the opinion in Megilah 11a that Hodu and Kush are adjacent. (PF)
Who are "Asarai"?
Rashi: Those who pray to Me.
Radak: Asarai Bas Putzi is the name of a nation or family on the other side of the Kush rivers.
Radak 1 : Hashem calls Yisrael so, for Ye'ater (He accedes) to them.
Malbim: They are idolaters who do all abominations.
Radak cites Targum Yonasan. Our text of Yonason does not give the reason. (PF)
What is the meaning of "Bas Putzi"?
Rashi, Targum Yonasan: The congregations of those whom I scattered.
Refer to 3:10:2:2, 4.
What gift will they bring?
Radak: They will bring Yisrael to Yerushalayim, like it says "Hoy Eretz Tziltzal Kenafayim Asher me'Ever l'Naharei Kush", ba'Es ha'Hi Yuval Shai la'Shem Tzevakos Im Memushach u'Morat" (Yeshayah 18:1, 7). Targum Yonasan says, with mercy they will return the Galus of My nation that was exiled, and they will bring them for a Korban 1 .
Malbim: "V'Hevi'u Es Kol Acheichem... Minchah" (Yeshayah 66:20). These nations will bring those who were cast off in Galus Sancheriv.
