Numbers 26:60-62

Young's Literal Translation

⁶⁰ And born to Aaron Nadab and Abihu, Eleazar and Ithamar;

⁶¹ and Nadab dieth -- Abihu also -- in their bringing near strange fire before Jehovah.

⁶² And their numbered ones are three and twenty thousand, every male from a son of a month and upwards, for they have not numbered themselves in the midst of the sons of Israel; for an inheritance hath not been given to them in the midst of the sons of Israel.
