Leviticus 25:25-30

25‘1If a 2fellow countryman of yours becomes so poor he has to sell part of his property, then his nearest kinsman is to come and buy back what his 3relative has sold. 26Or in case a man has no kinsman, but so 4recovers his means as to find sufficient for its redemption, 275then 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 property. 28But if 6he has not found sufficient means to get it back for himself, then what he has sold shall remain in the hands of its purchaser until the year of jubilee; but at the jubilee it shall 7revert, that 8he may return to his property.

29‘Likewise, if a man sells a dwelling house in a walled city, then his redemption right remains valid until a full year from its sale; his right of redemption lasts a full year. 30But if it is not bought back for him within the space of a full year, then the house that is in the walled city passes permanently to its purchaser throughout his generations; it does not 9revert in the jubilee.
