Numbers 26:61-63

American Standard Version

⁶¹ And Nadab and Abihu died, when they offered strange fire before Jehovah. ⁶² And they that were numbered of them were twenty and three thousand, every male 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.

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