Numbers 26:60

58These are the families of Levi: the family of the Libnites, the family of the Hebronites, the family of the Mahlites, the family of the Mushites, and the family of the Korahites. Kohath became the father of Amram.

59The name of Amram’s wife was Jochebed, the daughter of Levi, who was born to Levi in Egypt. She bore to Amram Aaron and Moses, and Miriam their sister.

60To Aaron were born Nadab and Abihu, Eleazar and Ithamar.

61Nadab and Abihu died when they offered strange fire before the LORD.

62Those who were counted of them were twenty-three thousand, every male from a month old and upward; for they were not counted among the children of Israel, because there was no inheritance given them among the children of Israel.
