Leviticus 25:26-27

New International Version

²⁶ If, however, there is no one to redeem it for them but later on they prosper^(A) and acquire sufficient means to redeem it themselves, ²⁷ they are to determine the value for the years^(B) since they sold it and refund the balance to the one to whom they sold it; they can then go back to their own property.^(C)
