These be the sons of Leah, which she bare unto Jacob in Padan-aram, with his daughter Dinah: all the souls of his sons and his daughters were thirty and three. Dinah. She and Serah (Genesis 46:17) are the only two females mentioned in this catalogue. Judging from the plan followed in other genealogical lists, respecting the introduction of female names, the insertion of the two women in this genealogy might have been dictated by reasons which, although well understood at the time, we may find it difficult to discover. Luther suggests that the reason of Dinah being mentioned might be, that she had become the housekeeper upon the death of Jacob's wives.
