בראשית, פרק ל׳, פסוק כ״א

The arrival of a single daughter among a long line of sons marks a striking shift in the family dynamic of Jacob and Leah. The record of her birth is unusually brief. Unlike the detailed accounts of her brothers, her arrival lacks the standard mention of a new pregnancy and offers no immediate explanation for the name she is given.

The absence of a reported conception leads to two distinct ways of understanding the events. A practical approach suggests that she was simply the twin sister of Zebulun, meaning there was no new pregnancy to announce [אבן עזרא, רד״ק, בכור שור, חזקוני, תולדות יצחק]. Another tradition, however, points to a miraculous occurrence. In this view, Leah originally conceived a male child, but ultimately delivered a girl [העמק דבר, תורה תמימה, שפתי כהן, דעת זקנים, חזקוני]. Some even suggest that the pregnancy actually began in Rachel's womb, and the two mothers miraculously swapped fetuses [הטור הארוך, פענח רזא, הדר זקנים, פרדס יוסף].

The catalyst for this miracle was Leah’s deep compassion and righteousness. Having already given birth to six sons, Leah realized that if she delivered another boy, her sister Rachel would be left with fewer sons than even the family's handmaids. Moved by pity, Leah prayed, and God answered by transforming the male fetus in her womb into a female [רש״י, רד״ק, ביאור יש״ר, רבנו בחיי]. Opinions differ on exactly when this divine intervention took place. Some maintain that her prayer occurred during the initial forty days of the child's formation, while others assert that God can alter a child's nature even in the final moments before birth [מזרחי, חומת אנך, צאינה וראינה, דברי דוד]. The sequence of events is sometimes seen as a hint to this very miracle, suggesting a hidden, internal transformation took place between conception and delivery [חומת אנך].

Unlike the births of her brothers, no explicit reason is provided for the name Dinah. A few scholars suggest this omission reflects a cultural reality: the birth of a daughter did not typically prompt the same public declarations of thanksgiving as a son, and the account simply serves to note her unique status as Jacob's only daughter [רשב״ם, בכור שור]. The primary approach among commentators, however, connects her name to the concept of judgment. Her name forever commemorates the just judgment Leah imposed upon herself to protect her sister's honor [רש״י, תורה תמימה, צאינה וראינה]. Additionally, it may reflect the strict attribute of divine judgment associated with a daughter's birth following a succession of six sons [רבנו בחיי, אלשיך]. Ultimately, her arrival serves as the final chapter in Leah's childbearing, bringing a definitive close to her series of sons [רבנו בחיי].
