Numbers 26:60-62

American Standard Version

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