Abba Halifa of Keruya asked Rabbi Hiyya bar Abba why reported that 70 people from Jacob's household came to Egypt, while enumerated only 69 individuals. Rabbi Hiyya reported that Rabbi Hama bar Hanina taught that the seventieth person was the mother of Moses, Jochebed, who was conceived on the way from Canaan to Egypt and born as Jacob's family passed between the city walls as they entered Egypt, for reported that Jochebed "was born to Levi in Egypt," implying that her conception was not in Egypt.
