Bamidbar 3:38-40

Orthodox Jewish Bible

³⁸ And those that encamp in front of the Mishkan toward the east, even in front of the Ohel Mo’ed eastward, shall be Moshe, and Aharon and his banim, shomrim mishmeret HaMikdash (standing guard duty over the holy area) on behalf of the Bnei Yisroel; and the zar that shall encroach shall be put to death.

³⁹ All that were counted of the Levi’im, which Moshe and Aharon numbered at the command of Hashem, by their mishpekhot, all the zakhar from a month old and upward, were twenty and two thousand.

⁴⁰ And Hashem said unto Moshe, Count all the bechor of the zakhar of the Bnei Yisroel from a month old and upward, and calculate the total by their shmot.
