Numbers 26:61-63 English Standard Version Anglicised (ESVUK)
61 But Nadab and Abihu died when they offered unauthorized fire before the Lord. 62 And those listed were 23,000, every male from a month old and upwards. For they were not listed among the people of Israel, because there was no inheritance given to them among the people of Israel.
63 These were those listed by Moses and Eleazar the priest, who listed the people of Israel in the plains of Moab by the Jordan at Jericho.
