57 And these are they that were numbered of the Levites after 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 the Levites: the family of the Libnites, the family of the Hebronites, the family of the Mahlites, the family of the Mushites, the family of the Korathites. And Kohath begat Amram. 59 And the name of Amram's wife was Jochebed, the daughter of Levi, whom her mother bare to Levi in Egypt: and she bare unto Amram Aaron and Moses, and Miriam their sister. 60 And unto Aaron was born Nadab, and Abihu, Eleazar, and Ithamar. 61 And Nadab and Abihu died, when they offered strange fire before the LORD. 62 And those that were numbered of them were twenty and three thousand, all males from a month old and upward: for they were not numbered among the children of Israel, because there was no inheritance given them among the children of Israel.
Levi was God's tribe, a tribe that was to have no inheritance with the rest in the land of Canaan, and therefore was not numbered with the rest, but by itself; so it had been numbered in the beginning of this book at Mount Sinai, and therefore came not under the sentence passed upon all that were then numbered, that none of them should enter Canaan but Caleb and Joshua; for of the Levites that were not numbered with them, nor were to go forth to war, Eleazar and Ithamar, and perhaps others who were above twenty years old then (as appears, Numbers 4:16; Numbers 4:28), entered Canaan; and yet this tribe, now at its second numbering, had increased but 1000, and was still one of the smallest tribes. Mention is made here of the death of Nadab and Abihu for offering strange fire, as before of the sin and punishment of Korah, because these things happened to them for ensamples.
