Numbers 26:61 KJV

59And 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.

60And unto Aaron was born Nadab, and Abihu, Eleazar, and Ithamar.

61And Nadab and Abihu died, when they offered strange fire before the LORD.

62And 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.

63These are they that were numbered by Moses and Eleazar the priest, who numbered the children of Israel in the plains of Moab by Jordan near Jericho.
