וּפִתְּח֨וּ שְׁעָרַ֧יִךְ תָּמִ֛יד יוֹמָ֥ם וָלַ֖יְלָה לֹ֣א יִסָּגֵ֑רוּ לְהָבִ֤יא אֵלַ֙יִךְ֙ חֵ֣יל גּוֹיִ֔ם וּמַלְכֵיהֶ֖ם נְהוּגִֽים׃
네 성문이 항상 열려 주야로 닫히지 아니하리니 이는 사람들이 네게로 열방의 재물을 가져오며 그 왕들을 포로로 이끌어 옴이라
Rashi on Isaiah
And they shall open your gates always Heb. וּפִתְּחוּ. This is an expression of opening in the strong conjugation (פִּעֵל), since their opening is a perpetual opening, a constant opening. Just as שַׁבֵּר is an expression of breaking, so is פִּתְּחוּ an expression of opening. Tresoverts in O.F.
Ibn Ezra on Isaiah
ופתּחו Some say that וּפִחְּחוּ is the same as וּפֻתְּחוּ and they will be opened. According to others, And they will open, that is, the sons of strangers will open, etc.; this explanation is not improbable.—The sense of the whole verse is: the gates will be opened continually, day and night, by those that will bring in the abundance of nations.
Ibn Ezra on Isaiah
Their kings, that is, those who had been their kings. And that their kings may be brought. Comp. To bind their kings with chains (Ps. 149:8)
