הִקָּבְצ֥וּ וָבֹ֛אוּ הִֽתְנַגְּשׁ֥וּ יַחְדָּ֖ו פְּלִיטֵ֣י הַגּוֹיִ֑ם לֹ֣א יָדְע֗וּ הַנֹּֽשְׂאִים֙ אֶת־עֵ֣ץ פִּסְלָ֔ם וּמִתְפַּלְלִ֔ים אֶל־אֵ֖ל לֹ֥א יוֹשִֽׁיעַ׃
Rashi on Isaiah
approach Heb. הִתְנַגְּשׁוּ, an expression of approaching (הַגָּשָׁה) and the ‘nun’ is attached to it, as one says “they were struck (הִתְנַגְּפוּ)”; “they will be struck (יִתְנַגְּפוּ).”
Ibn Ezra on Isaiah
הקבצו ובאו התנגשו Assemble yourselves and come, draw near. These are imperatives.
Rashi on Isaiah
you survivors of the nations who survived the sword of Nebuchadnezzar.
