Numbers 3:49

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

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

49Moses took the redemption money from those who exceeded the number of those who were redeemed by the Levites;

50from the firstborn of the children of Israel he took the money, one thousand three hundred sixty-five shekels, according to the shekel of the sanctuary;

51and Moses gave the redemption money to Aaron and to his sons, according to the LORD’s word, as the LORD commanded Moses.
