Shechem son of Hamor once assembled a troupe of girls with tambourines to play outside the tent of Dinah, and when she "went out to see them" (Genesis 34:1), he carried her off. From that violence was born a daughter named Osenath. The sons of Jacob wanted to kill the child, afraid that the people of the land would spread scandal about their father's house.
Jacob chose mercy instead of blood. He engraved the Holy Name on a metal plate, hung it as an amulet around the baby's neck, and sent her away into the wilderness. The midrash says the Holy One, blessed be He, saw the scene and sent the archangel Michael down to guide the child to safety.
Michael led Osenath all the way to Egypt, into the household of Potiphera, priest of On. Why there? Because Osenath was destined to become the wife of Joseph (Genesis 41:45). When Pharaoh later gave Joseph the priest's daughter in marriage, she was not a stranger to Israel but Dinah's own granddaughter — the one Jacob's sons had wanted to kill.
The midrash from Pirkei de-Rabbi Eliezer chapter 38 teaches that rejected children are sometimes the threads God uses to bind the generations together. The baby Jacob refused to destroy became the mother of Manasseh and Ephraim, the two tribes of Joseph who shaped Israel's future.
