Numbers 3:43-48 World English Bible (WEB)

43. All the firstborn males according to the number of names, from a month old and upward, of those who were counted of them, were twenty-two thousand two hundred seventy-three.

44. Yahweh spoke to Moses, saying,

45. “Take the Levites instead of all the firstborn among the children of Israel, and the livestock of the Levites instead of their livestock; and the Levites shall be mine. I am Yahweh.

46. For the redemption of the two hundred seventy-three of the firstborn of the children of Israel, who exceed the number of the Levites,

47. you shall take five shekels apiece for each one; after the shekel of the sanctuary you shall take them (the shekel is twenty gerahs):

48. and you shall give the money, with which their remainder is redeemed, to Aaron and to his sons.”
