Numbers 26:57-64

57These were the Levites who were counted by their clans: through Gershon, the Gershonite clan; through Kohath, the Kohathite clan; through Merari, the Merarite clan.

58These also were Levite clans: the Libnite clan, the Hebronite clan, the Mahlite clan, the Mushite clan, the Korahite clan. (Kohath was the forefather of Amram;

59the name of Amram’s wife was Jochebed, a descendant of Levi, who was born to the Levites in Egypt. To Amram she bore Aaron, Moses and their sister Miriam.

60Aaron was the father of Nadab and Abihu, Eleazar and Ithamar.

61But Nadab and Abihu died when they made an offering before the Lord with unauthorized fire.)

62All the male Levites a month old or more numbered 23,000. They were not counted along with the other Israelites because they received no inheritance among them.

63These are the ones counted by Moses and Eleazar the priest when they counted the Israelites on the plains of Moab by the Jordan across from Jericho.

64Not one of them was among those counted by Moses and Aaron the priest when they counted the Israelites in the Desert of Sinai.
