'Redeemed' in the Bible

and thou shalt give the money, wherewith the odd number of them is redeemed, unto Aaron and to his sons.

And Moses took the redemption-money from them that were over and above them that were redeemed by the Levites;

And those that are to be redeemed of them from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary (the same is twenty gerahs).
