Bamidbar 3:40-42

Orthodox Jewish Bible

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.

⁴¹ And thou shalt take the Levi’im for Me—I am Hashem—instead of all the bechor among the Bnei Yisroel; and the cattle of the Levi’im instead of all the firstlings among the cattle of the Bnei Yisroel.

⁴² And Moshe counted, as Hashem commanded him, all the bechor among the Bnei Yisroel.
