Numbers 26:60-62

New Living Translation

⁶⁰ To Aaron were born Nadab, Abihu, Eleazar, and Ithamar. ⁶¹ But Nadab and Abihu died when they burned before the Lord the wrong kind of fire, different than he had commanded.

⁶² The men from the Levite clans who were one month old or older numbered 23,000. But the Levites were not included in the registration of the rest of the people of Israel because they were not given an allotment of land when it was divided among the Israelites.
