Genesis 30:21

21.And afterward she bare a daughter. It is not known whether Jacob had any other daughter; for it is not uncommon in Scripture, when genealogies are recorded, to omit the women, since they do not bear their own name, but lie concealed under the shadow of their husbands. Meanwhile, if anything worthy of commemoration occurs to any women, especial mention is then made of them. This was the case with Dinah, on account of the violence done to her; of which more will be said hereafter. But whereas the sons of Jacob subsequently regarded it as an indignity that their sister should marry one of another nation; and as Moses records nothing of any other daughters, either as being settled in the land of Canaan, or married in Egypt, it is probable that Dinah was the only one born to him.
