⁴⁷ you shall take ^(A)five shekels^[a] per head; you shall take them according to ^(B)the shekel of the sanctuary (the shekel of twenty gerahs^[b]), ⁴⁸ and give the money to Aaron and his sons as the redemption price for those who are over.” ⁴⁹ So Moses took the redemption money from those who were over and above those redeemed by the Levites.
