כָּל־יֹשְׁבֵ֥י תֵבֵ֖ל וְשֹׁ֣כְנֵי אָ֑רֶץ כִּנְשֹׂא־נֵ֤ס הָרִים֙ תִּרְא֔וּ וְכִתְקֹ֥עַ שׁוֹפָ֖ר תִּשְׁמָֽעוּ׃ (ס)
Vede, todos vós, habitantes do mundo, e vós os moradores da terra, quando se arvorar a bandeira nos montes; e ouvi, quando se tocar a trombeta.
Siftei Chakhamim
A symbol and a reminder. That is to say that the term נס ["banner"] has the connotation of something high [which is visible to all], similar to כנס על הגבעה ["like a banner on top of the hill"] (Yeshayahu 30:17), and כנשוא נס הרים ["a banner raised over the mountains"] (Yeshayahu 18:3).
