Numbers 26:57-65 - The Tribe Of Levi
57 These [are] the ones counted of the Levites according to their clans: of Gershon, the clan of the Gershonites; of Kohath, the clan of the Kohathites; of Merari, the clan of the Merarites. 58 These [are] the clans of Levi: the clan of the Libnites, the clan of the Hebronites, the clan of the Mahlites, the clan of the Mushites, the clan of the Korahites. Kohath fathered Amram. 59 The name of the wife of Amram [was] Jochebed, the daughter of Levi, whose [mother] bore her for Levi in Egypt; she bore to Amram: Aaron and Moses and their sister Miriam. 60 To Aaron were born Nadab and Abihu, Eleazar and Ithamar. 61 But Nadab and Abihu died when they presented strange fire {before} Yahweh. 62 The ones counted were twenty-three thousand, every male from {a month old} and above, because they were not counted in the midst of the {Israelites} since no inheritance was given to them in the midst of the {Israelites}.
63 These [were] the ones counted by Moses and Eleazar the priest, who counted the {Israelites} on the desert-plateau of Moab on [the] Jordan [across] Jericho. 64 And among these there was not a man of those counted by Moses and Aaron the priest, who counted the {Israelites} in the desert of Sinai. 65 For Yahweh said to them, "They will surely die in the desert." And not a man was left over from them, except Caleb son of Jephunneh and Joshua son of Nun.
