כִּֽי־מִפְּנֵ֥י חֲרָב֖וֹת נָדָ֑דוּ מִפְּנֵ֣י ׀ חֶ֣רֶב נְטוּשָׁ֗ה וּמִפְּנֵי֙ קֶ֣שֶׁת דְּרוּכָ֔ה וּמִפְּנֵ֖י כֹּ֥בֶד מִלְחָמָֽה׃ (ס)
Denn vor den Schwertern flüchten sie, vor dem gezückten Schwert und vor dem gespannten Bogen und vor des Krieges Schwere.
Rashi on Isaiah
Since because of the swords they wandered (I.e.,) my people (wandered).
Ibn Ezra on Isaiah
For they fled from the swords. They, that are wandering about, are fleeing because of the king of Assyria.
Rashi on Isaiah
the outstretched sword (נְטוּשָׁה), spread over the surface of the earth, as (I Sam. 30:16) “And behold, they were scattered (נְטוּשִׁים) over the entire landscape,” (II Sam. 5: 18) “And spread out (וַיִּנָּטְשׁוּ) in the Valley of Rephaim.” Another explanation is that נְטוּשָׁה is like לְטוּשָׁה, sharp. All letters whose sources are close to being from one place, (i.e., from one speech organ,) are interchangeable with one another, the ‘nun’ with the ‘lamed,’ as in the case stated (in Nehemiah 13: 7): “To make him a chamber (נִשְׁכָּה),” like לִשְׁכָּה.
