וַתֵּ֣רֶא רָחֵ֗ל כִּ֣י לֹ֤א יָֽלְדָה֙ לְיַעֲקֹ֔ב וַתְּקַנֵּ֥א רָחֵ֖ל בַּאֲחֹתָ֑הּ וַתֹּ֤אמֶר אֶֽל־יַעֲקֹב֙ הָֽבָה־לִּ֣י בָנִ֔ים וְאִם־אַ֖יִן מֵתָ֥ה אָנֹֽכִי׃
E Raquel viu que não dava filhos a Yaakov, e Raquel teve inveja de sua irmã, e disse a Yaakov: Dá-me filhos, e se não, eu morro.
Zohar
And should it be pointed out that even Jacob was not spared this enmity in wives, as we read that “Rachel was jealous of Leah” (Gen. xxx, I), then would I answer: Surely so! and how could it be otherwise? For the whole longing and the most ardent desire of the lower world (symbolized by Rachel) is to be in all outer seeming like unto the upper world (symbolized by Leah), and to usurp its powers and reign in its stead.
