Bamidbar 26:61-63

Orthodox Jewish Bible

⁶¹ And Nadav and Avihu died, when they offered eish zarah before Hashem.

⁶² And those that were numbered of them were 23,000, kol zachar from a month old and upward: for they were not numbered among the Bnei Yisroel, because there was no nachalah given them among the Bnei Yisroel.

⁶³ These are they that were numbered by Moshe and Eleazar HaKohen, who numbered the Bnei Yisroel in the arevot Mo’av (plains of Moav) by Yarden near Yericho.
