Numbers 3:46-50

And as a redemption price for the 273 of the firstborn of the sons of Israel who are in excess of the number of the Levites,

you shall take five shekels apiece, per head; you shall take them in terms of the shekel of the sanctuary (the shekel is twenty gerahs),

and you shall give the money, the redemption price of those who are in excess among them, to Aaron and to his sons.”

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

from the firstborn of the sons of Israel he took the money in terms of the shekel of the sanctuary, 1,365.
