Numbers 3:39-49 Holman Christian Standard Bible (HCSB)
39 The total number of all the Levite males one month old or more that Moses and Aaron[a] registered by their clans at the Lord’s command was 22,000.
Redemption of the Firstborn
40 The Lord told Moses: “Register every firstborn male of the Israelites one month old or more, and list their names. 41 You are to take the Levites for Me—I am Yahweh—in place of every firstborn among the Israelites, and the Levites’ cattle in place of every firstborn among the Israelites’ cattle.” 42 So Moses registered every firstborn among the Israelites, as the Lord commanded him. 43 The total number of the firstborn males one month old or more listed by name was 22,273.
44 The Lord spoke to Moses again: 45 “Take the Levites in place of every firstborn among the Israelites, and the Levites’ cattle in place of their cattle. The Levites belong to Me; I am Yahweh. 46 As the redemption price for the 273 firstborn Israelites who outnumber the Levites, 47 collect five shekels for each person, according to the standard sanctuary shekel—20 gerahs to the shekel. 48 Give the money to Aaron and his sons as the redemption price for those who are in excess among the Israelites.”
49 So Moses collected the redemption money from those in excess of the ones redeemed by the Levites.
