But if she shall bear a maid child, she shall be unclean two weeks, according to the custom of her monthly courses. And she shall remain in the blood of her purification sixty-six days.
וְאִם־נְקֵבָ֣ה תֵלֵ֔ד וְטָמְאָ֥ה שְׁבֻעַ֖יִם כְּנִדָּתָ֑הּ וְשִׁשִּׁ֥ים יוֹם֙ וְשֵׁ֣שֶׁת יָמִ֔ים תֵּשֵׁ֖ב עַל־דְּמֵ֥י טָהֳרָֽה׃
2 Church Fathers comment on this verse
What is the reason that, ‘as soon as ... give birth to the female sex’, the period of purification is extended? Is it due to the fact that the female is regarded as more esteemed than the male, or is it because the development of the female in the womb requires more time, allowing the male child to undergo initial formation in forty days, while the female child takes eighty?
Some interpreted the variation in the days as a result of the increased effort demanded from mothers who give birth to daughters. Consequently, the law provided them with double the time for rest.
