The Tribe of Levi

57 These are the numberings of the Levites by clan: Gershon and the Gershonite clan, Kohath and the Kohathite clan, Merari and the Merarite clan. 58 The Levite clans also included: the Libnite clan, the Hebronite clan, the Mahlite clan, the Mushite clan, the Korahite clan. 59 Amram's wife was Jochebed, a descendant of Levi, born into the Levite family during the Egyptian years. Jochebed bore Aaron, Moses, and their sister Miriam to Amram. 60 Aaron was the father of Nadab and Abihu, Eleazar and Ithamar; 61 however, Nadab and Abihu died when they offered unauthorized sacrifice in the presence of God. 62 The numbering of Levite males one month and older came to 23,000. They hadn't been counted in with the rest of the People of Israel because they didn't inherit any land.

Commentary on Numbers 26:57-62

(Read Numbers 26:57-62)

Levi was God's tribe; therefore it was not numbered with the rest, but alone. It came not under the sentence, that none of them should enter Canaan excepting Caleb and Joshua.
