Parashas Shemos
וַתַּ֥הַר הָאִשָּׁ֖ה וַתֵּ֣לֶד בֵּ֑ן וַתֵּ֤רֶא אֹתוֹ֙ כִּי־ט֣וֹב ה֔וּא וַֽתִּצְפְּנֵ֖הוּ שְׁלֹשָׁ֥ה יְרָחִֽים׃
The woman conceived and bore a son; and when she saw how beautiful he was, she hid him for three months.
Torah Temimah points to R’ Yehudah bar Zevina — Sotah 12a (verified).
ותהר האשה ותלד — א״ר יהודה בר זבינא: מקיש לידתה להורתה, מה הורתה שלא בצער אף לידתה שלא בצער, מכאן לנשים צדקניות שלא היו בפתקה של חוה.
English: “And the woman conceived and bore” — R’ Yehudah bar Zevina said: Her birth is compared to her conception; just as her conception was without pain, so her birth was without pain. From here [we learn] that righteous women were not included in the decree of Chava.
Custom — gezerah shavah / comparison of conception and birth.
Chazal teach that the birth of Moshe, like the conception, was without the pain of Chava’s curse.
