Shechem, the son of Hamor, assembled girls together playing on tambourines outside the tent of Dinah, and when she " went out to see them," he carried her off, and she bare him Osenath. The sons of Jacob wished to kill her, lest the people of the land should begin to talk scandal of the house of their father. Jacob, however, engraved the holy Name on a metal plate, suspended it upon her neck, and sent her away. All this being observed before the Holy One — blessed be He! — the angel Michael was sent down, who led her to Egypt, into the house of Potipherah; for Osenath was worthy to become the wife of Joseph.
