כִּי֩ ק֨וֹל כְּחוֹלָ֜ה שָׁמַ֗עְתִּי צָרָה֙ כְּמַבְכִּירָ֔ה ק֧וֹל בַּת־צִיּ֛וֹן תִּתְיַפֵּ֖חַ תְּפָרֵ֣שׂ כַּפֶּ֑יהָ אֽוֹי־נָ֣א לִ֔י כִּֽי־עָיְפָ֥ה נַפְשִׁ֖י לְהֹרְגִֽים׃ (פ)
Poiché ho sentito la voce di una donna in travaglio, L'angoscia da parte sua che genera il suo primo figlio, La voce della figlia di Sion, che ansima per il respiro, Che allarga le mani: 'Guai a me, adesso! perché la mia anima svenne davanti agli assassini.'
Zohar
"And Rivkah took the best clothes of her eldest son Esau" (Beresheet 27:15). These are the garments Esau took from Nimrod. They are the precious garments from Adam, which came to the hands of Nimrod, who used them when he hunted, as it is written, "He was a mighty hunter before Hashem" (Beresheet 10:9). And Esau went into the field, where he fought with and killed Nimrod, removing the garments from him. This is the meaning of "and Esau came from the field, and he was faint" (Beresheet 25:29). It has already been explained why it is here written, "And he was faint," and elsewhere, "for my soul faints before the slayers" (Yirmeyah 4:31). These are analogous. There it is written "faint" to refer to killing. Here too, there is killing, because Esau murdered Nimrod.
