Numbers 3:39-43

CLV(i) 39 All the ones being mustered of the Levites whom Moses and Aaron mustered at the bidding of Yahweh by their families, every male from a month old and upward were twenty-two thousand. 40 Yahweh said to Moses:Muster every firstborn male of the sons of Israel from a month old and upward and obtain the number of their names. 41 You will take the Levites for Me (I am Yahweh) instead of every firstborn among the sons of Israel, and the beasts of the Levites instead of every firstborn among the beasts of the sons of Israel. 42 So Moses mustered, just as Yahweh had instructed him, every firstborn among the sons of Israel. 43 And all the firstborn males by the number of the names, from a month old and upward, as they had been mustered, were twenty-two thousand two hundred and seventy-three.
