Komentaryo sa Exodo 2:3: Rashi, Chizkuni, Da'at Zekenim & Ibn Ezra

ולא יכלה עוד הצפינו AND SHE COULD NO LONGER CONCEAL HIM, because the Egyptians calculated the period from when he (Amram) took her back. She, however, bore him after a term of six months and one day — for a woman who gives birth to a child in the seventh month may do so in incomplete months (i. e. the seventh month of pregnancy may not be completed) (Niddah 38b) — and they (the Egyptians) made enquiry regarding her at the end of nine months (the normal term of pregnancy, but in this case three months after the child’s birth; therefore “she could no longer conceal him”).

ולא יכלה עוד הצפינו, “and she could not hide him any longer;” according to Rashi, she had given birth to him one day into the seventh month of her pregnancy. The Egyptians had demanded to examine her on the day following. If you were to ask that according to the Talmud in Sotah 12 Yocheved was already 3 months pregnant when her husband remarried her, how could Moses have been born after a six month pregnancy? We must therefore say that the Egyptians examined her already after six months after she had remarried. This would be nine months after she had become pregnant from her husband. The Egyptians knew that sometimes babies are born and survive after being born during the seventh month of pregnancy. Moses, on the other hand, was born three months after Yocheved had been remarried. This is why she could not hide him for longer than an additional three months.

ולא יכלה עוד הצפינו, “she could not (successfully) hide him any longer; Rashi comments here that the Egyptians had kept track of when Yocheved had finished serving as the King’s midwife, and calculated the earliest date that she could give birth to a child from her husband. At the end of nine months they checked her out. They had allowed for the fact that she might have been three months pregnant when appointed as midwife. This explains why she felt safe hiding her baby during the first three months.

גמא PAPER-REED — In the language of the Mishna it is called גמי (Shabbat 78a), and in old French junc. It is a flexible substance that offers resistance to the pressure of both soft and hard things (Sotah 12a).
