Numbers 26:65

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

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.

These are they that were numbered by Moses and Eleazar the priest, who numbered the children of Israel in the plains of Moab by Jordan near Jericho.

But among these there was not a man of them whom Moses and Aaron the priest numbered, when they numbered the children of Israel in the wilderness of Sinai.
