Numbers 26:58-62

These 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 fathered Amram.

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

And to Aaron were born Nadab and Abihu, Eleazar and Ithamar.

But Nadab and Abihu died when they offered strange fire before the Lord.

Those who were numbered of them were twenty-three thousand, every male from a month old and upward, for they were not numbered among the sons of Israel since no inheritance was given to them among the sons of Israel.
