Numbers 26:61-63

Revised Standard Version

⁶¹ But Nadab and Abi′hu died when they offered unholy fire before the Lord. ⁶² And those numbered of them were twenty-three thousand, every male from a month old and upward; for they were not numbered among the people of Israel, because there was no inheritance given to them among the people of Israel.

⁶³ These were those numbered by Moses and Elea′zar the priest, who numbered the people of Israel in the plains of Moab by the Jordan at Jericho.
