Numbers 3:40-42

World English Bible

⁴⁰ Yahweh said to Moses, “Count all the firstborn males of the children of Israel from a month old and upward, and take the number of their names. ⁴¹ You shall take the Levites for me—I am Yahweh—instead of all the firstborn among the children of Israel; and the livestock of the Levites instead of all the firstborn among the livestock of the children of Israel.”

⁴² Moses counted, as Yahweh commanded him, all the firstborn among the children of Israel.
