Numbers 26:60-62

King James Version

⁶⁰ And unto Aaron was born Nadab, and Abihu, Eleazar, and Ithamar.

⁶¹ And Nadab and Abihu died, when they offered strange fire before the Lord.

⁶² And those that were numbered of them were twenty and three thousand, all males 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.
