[א] אשה – אין לי אלא אשה גמורה. בת יום א' מנין? ת"ל "ואשה". מכאן אמרו: בת יום א' לנדה. בת עשרה ימים לזיבה.
1) (Vayikra 15:19) ("And a woman, if she will have a flow, (if) blood shall be her flow in her flesh, seven days shall she be in her niddah state, and whoever touches her shall be unclean until the evening.") "And a woman": This tells me only of a woman. Whence do we derive that even a one-day-old child (is included in this context of niddah)? From "And a woman" — whence they ruled: A one-day-old child for niddah; a ten-day-old child for zivah (seven days of niddah flow and three additional days of zivah flow).
