American Standard Version

⁴⁶ And for ^[a]the redemption of the two hundred and threescore and thirteen of the first-born of the children of Israel, that are over and above the number of the Levites, ⁴⁷ thou shalt take five shekels apiece by the poll; after the shekel of the sanctuary shalt thou take them (the shekel is twenty gerahs): ⁴⁸ and thou shalt give the money, wherewith the odd number of them is redeemed, unto Aaron and to his sons.
