ותהרין וגו'. אַעַ"פִּ שֶׁאֵין הָאִשָּׁה מִתְעַבֶּרֶת מִבִּיאָה רִאשׁוֹנָה, אֵלּוּ שָׁלְטוּ בְעַצְמָן וְהוֹצִיאוּ עֶרְוָתָן לַחוּץ וְנִתְעַבְּרוּ מִבִּיאָה רִאשׁוֹנָה:

ותהרין וגו AND THEY BECAME PREGNANT, ETC. — Even though a woman does not become pregnant from the first intercourse, these [women] mastered themselves and took out their hymens; and they became pregnant from the first intercourse (Genesis Rabbah 51:9).
