וְאִשָּׁה֙ כִּֽי־תִהְיֶ֣ה זָבָ֔ה דָּ֛ם יִהְיֶ֥ה זֹבָ֖הּ בִּבְשָׂרָ֑הּ שִׁבְעַ֤ת יָמִים֙ תִּהְיֶ֣ה בְנִדָּתָ֔הּ וְכָל־הַנֹּגֵ֥עַ בָּ֖הּ יִטְמָ֥א עַד־הָעָֽרֶב׃
At kapag ang isang babae ay may lumalabas na agos, at dugo ang kanyang agos mula sa kanyang laman, pitong araw siyang mananatili sa kanyang pagkahiwalay; at sinumang humipo sa kanya ay magiging marumi hanggang sa gabi.
Leviticus
Speak to Bnei Yisroel, saying, when a woman conceives and gives birth to a male child she will be ritually unclean for seven days; as the days of her menstrual flow, she will be unclean.
