Leviticus 25:25-30

25“If your brother becomes poor and sells some of his property, then his nearest kinsman may come and redeem what his brother has sold.

26If a man has no kinsman-redeemer, but he himself recovers and finds sufficient means to redeem it,

27then let him reckon the years since its sale and restore the surplus to the man to whom he sold it. Then he will return to his property.

28But if he is not able to get it back for himself, then what he has sold is to remain in the hand of the one who has bought it until the Year of Jubilee. Then in the Jubilee it shall be released, so he may return to his property.

29“If a man sells a house in a walled city, then he may redeem it within a whole year after it has been sold. For a full year he has the right of redemption.

30But if it is not redeemed within the space of a full year, then the house that is in the walled city will belong permanently to the one who bought it throughout his generations. It will not be released in the Jubilee.
