'Redemption money' in the Bible

If a ransom is set on him, he will pay the redemption money for his life according to all that is set on him.

If there are yet many years, according unto them shall he return his redemption money out of the money that he was bought for;

and if there remain but few years unto the year of jubilee, then he shall reckon with him; according unto his remaining years of service shall he give him back his redemption money.

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

and Moses gave the redemption-money unto Aaron and to his sons, according to the word of Jehovah, as Jehovah commanded Moses.
