Or HaChaim on Genesis 35:17/אור החיים על בראשית ל״ה:י״ז

1 אל תיראי כי גם זה לך בן. "Do not fear, for this one too is a son for you." What exactly was Rachel's fear which the midwife tried to alleviate? Assuming that Rachel was afraid to die, how did the midwife's words relieve Rachel's fears by saying "this one too is a son for you?" We also have to analyse the midwife's use of the word גם, "also."

2In order to understand this we must refer to Bereshit Rabbah 82,8 that whereas a twin sister was born with all the other sons of Jacob, Benjamin's birth was accompanied by the birth of two twin sisters. This is why the midwife told Rachel that she should not be afraid to die but that her special difficulties were due to her giving birth to triplets, something that had not been the case when she gave birth to Joseph. The word גם was a reference to the births which would accompany the birth of Benjamin.

3She may also have hinted at the statement we find in Niddah 31 that if a mother experiences difficulties when giving birth to a male child this does not threaten her life, whereas if she experiences similar difficulties when giving birth to a female child this does endanger her life. This is why the midwife reassured Rachel saying that the baby about to be born was definitely a boy.
