Numbers 3:40-51

Yahweh said to Moses, Number all the firstborn males of the children of Israel from a month old and upward, and take the number of their names.

You shall take the Levites for me (I am Yahweh) instead of all the firstborn among the children of Israel; and the cattle of the Levites instead of all the firstborn among the cattle of the children of Israel:

and Moses numbered, as Yahweh commanded him, all the first- born among the children of Israel.

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

Yahweh spoke to Moses, saying,

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

For the redemption of the two hundred seventy-three of the firstborn of the children of Israel, that are over and above [the number of] the Levites,

you shall take five shekels apiece by the poll; after the shekel of the sanctuary shall you take them (the shekel is twenty gerahs):

and you shall give the money, with which the odd number of them is redeemed, to Aaron and to his sons.

Moses took the redemption-money from those who were over and above those who were redeemed by the Levites;

from the firstborn of the children of Israel took he the money, one thousand three hundred sixty-five [shekels], after the shekel of the sanctuary:

and Moses gave the redemption-money to Aaron and to his sons, according to the word of Yahweh, as Yahweh commanded Moses.
