Numbers 26:60-62

New Revised Standard Version, Anglicised Catholic Edition

⁶⁰ To Aaron were born Nadab, Abihu, Eleazar, and Ithamar. ⁶¹ But Nadab and Abihu died when they offered unholy fire before the Lord. ⁶² The number of those enrolled was twenty-three thousand, every male one month old and upwards; for they were not enrolled among the Israelites because there was no allotment given to them among the Israelites.
