There was a man in the land of Egypt from the seed of Levi, and his name was Amram son of Kehat son of Levi son of Israel. And he went and took a wife - Yocheved [(who was born to Levi (Parshat Pinchas 26), and elsewhere it says Levi's wife was called)] daughter of Levi, his father's sister. And she was one hundred and twenty-six years old [this is year 2364, for she was born in year 2238 when they descended to Egypt].
And the woman conceived and bore a daughter and called her name Miriam, for in those days the Egyptians embittered the lives of the children of Israel. And she conceived again and bore a son and called his name Aharon, for in the days of her pregnancy Pharaoh began to spill the blood of the male children of Israel [Sefer HaYashar].
