“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.”
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.
