Numbers 3:40-51

40Then the Lord said to Moses, “Number all the firstborn males of the Israelites from a month old and upward, and take the number of their names.

41And take the Levites for me – I am the Lord – instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of all the firstborn of the livestock of the Israelites.”

42So Moses numbered all the firstborn males among the Israelites, as the Lord had commanded him.

43And all the firstborn males, by the number of the names from a month old and upward, totaled 22,273.

44Then the Lord spoke to Moses:

45“Take the Levites instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of their livestock. And the Levites will be mine. I am the Lord.

46And for the redemption of the 273 firstborn males of the Israelites who exceed the number of the Levites,

47collect five shekels for each one individually; you are to collect this amount in the currency of the sanctuary shekel (this shekel is twenty gerahs).

48And give the money for the redemption of the excess number of them to Aaron and his sons.”

49So Moses took the redemption money from those who were in excess of those redeemed by the Levites.

50From the firstborn males of the Israelites he collected the money, 1,365 shekels, according to the sanctuary shekel.

51Moses gave the redemption money to Aaron and his sons, according to the word of the Lord, as the Lord had commanded Moses.
