Numbers 26:60-65

26:60 And to Aaron were born Nadab and Abihu, Eleazar and Ithamar. 26:61 But Nadab and Abihu died when they offered strange fire before the Lord. 26:62 Those of them who were numbered were 23,000, all males from a month old and upward, for they were not numbered among the Israelites; no inheritance was given to them among the Israelites.

26:63 These are those who were numbered by Moses and Eleazar the priest, who numbered the Israelites in the plains of Moab along the Jordan River opposite Jericho. 26:64 But there was not a man among these who had been among those numbered by Moses and Aaron the priest when they numbered the Israelites in the wilderness of Sinai. 26:65 For the Lord had said of them, “They will surely die in the wilderness.” And there was not left a single man of them, except Caleb son of Jephunneh and Joshua son of Nun.
