Leviticus 25:25-28

25‘If a fellow countryman of yours becomes so poor he has to sell some of his property, then his nearest relative is to come and buy back (redeem) what his relative has sold.

26Or in case a man has no relative [to redeem his property], but he has become more prosperous and has enough to buy it back,

27then he shall calculate the years since its sale and refund the balance to the man to whom he sold it, and so return to his [ancestral] property.

28But if he is unable to redeem it, then what he has sold shall remain in the hands of the purchaser until the Year of Jubilee; but at the Jubilee it shall revert, and he may return to his property.
