Numbers 26:59

56 As it is ordered by the decision of the Lord, let distribution be made between those who are more in number and those who are less.

57 These were those of the Levites who were numbered by their families: of Gershon, the family of the Gershonites: of Kohath, the family of the Kohathites: of Merari, the family of the Merarites.

58 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, the family of the Korahites. And Kohath was the father of Amram.

59 Amram's wife was Jochebed, the daughter of Levi, whom he had in Egypt: by Amram she had Moses and Aaron and their sister Miriam.

60 Aaron's sons were Nadab and Abihu, Eleazar and Ithamar.

61 Death overtook Nadab and Abihu when they made an offering of strange fire before the Lord.

62 Of these, twenty-three thousand males, from one month old and over, were numbered: they were not numbered with the rest of the children of Israel, for they had no heritage among the children of Israel.
