בְּטֶ֥רֶם תָּחִ֖יל יָלָ֑דָה בְּטֶ֨רֶם יָב֥וֹא חֵ֛בֶל לָ֖הּ וְהִמְלִ֥יטָה זָכָֽר׃
Ona bowiem, zanim dreszcz uczuje porodzi, zanim ogarnie ją ból powije dzieci męzkie.
Rashi on Isaiah
When she has not yet travailed When Zion has not yet travailed with birth pangs, she has borne her children; that is to say that her children will gather into her midst, which was desolate and bereft of them, and it is as though she bore them now without birth pangs, for all the nations will bring them into her midst.
Ibn Ezra on Isaiah
תחיל She travailed. Comp. חיל trembling (Ps. 45:7). Before she travailed she brought forth. This is a figurative expression, indicating, that the Israelites will return to Zion, without any difficulty, like a woman, that bears children without troubles.
Rashi on Isaiah
she has been delivered of a male child Heb. וְהִמְלִיטָה. Any emerging of an embedded thing is called הַמְלָטָה. And הַמְלָטָה is esmoucer, or eschamocier in O.F., to allow to escape.
