כִּ֤י יְבִֽיאֲךָ֙ יְהוָ֣ה אֱלֹהֶ֔יךָ אֶל־הָאָ֕רֶץ אֲשֶׁר־אַתָּ֥ה בָא־שָׁ֖מָּה לְרִשְׁתָּ֑הּ וְנָשַׁ֣ל גּֽוֹיִם־רַבִּ֣ים ׀ מִפָּנֶ֡יךָ הַֽחִתִּי֩ וְהַגִּרְגָּשִׁ֨י וְהָאֱמֹרִ֜י וְהַכְּנַעֲנִ֣י וְהַפְּרִזִּ֗י וְהַֽחִוִּי֙ וְהַיְבוּסִ֔י שִׁבְעָ֣ה גוֹיִ֔ם רַבִּ֥ים וַעֲצוּמִ֖ים מִמֶּֽךָּ׃
When the LORD thy God shall bring thee into the land whither thou goest to possess it, and shall cast out many nations before thee, the Hittite, and the Girgashite, and the Amorite, and the Canaanite, and the Perizzite, and the Hivite, and the Jebusite, seven nations greater and mightier than thou;
Rashi
ונשל This is an expression denoting casting away, and throwing to a distance, and similar is, (Deuteronomy 19:5) “and the iron flies off" (ונשל).
Ibn Ezra
fell from, “your olives will drop off” [28: 40] (the nun here is part of the triliteral root).
Rashbam
ונשל, he threw. If one uproots, or separates anything its position where it was firmly attached is described in such terms. Compare Deuteronomy 28,40 כי ישל זיתיך, “for your olives will drop off.” Compare also Deut. 19,5 ונשל הברזל מן העץ, “the iron (axe) will fall off the handle.”
