Leviticus 25:51

If there be yet many years behind, according unto them he shall give again the price of his redemption out of the money that he was bought for.

Cross-reference

Leviticus 25:24 establishes redemption for land, while this verse applies the same principle to persons—both part of the Jubilee laws.

Leviticus 27:18 similarly calculates dedication price based on years until Jubilee, reinforcing the same redemption formula.
