Numbers 3:47-51

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.

Then Moses gave the redemption money to Aaron and to his sons, at the command of the Lord, just as the Lord had commanded Moses.
