Leviticus 25:31

27 he shall calculate the years since its sale, repay the balance to the man to whom he sold it, and return to his property.

28 But if he cannot obtain enough to repay him, what he sold will remain in possession of the buyer until the Year of Jubilee. In the Jubilee, however, it is to be released, so that he may return to his property.

29 If a man sells a house in a walled city, he retains his right of redemption until a full year after its sale; during that year it may be redeemed.

30 If it is not redeemed by the end of a full year, then the house in the walled city is permanently transferred to its buyer and his descendants. It is not to be released in the Jubilee.

31 But houses in villages with no walls around them are to be considered as open fields. They may be redeemed, and they shall be released in the Jubilee.

32 As for the cities of the Levites, the Levites always have the right to redeem their houses in the cities they possess.

33 So whatever belongs to the Levites may be redeemed—a house sold in a city they possess—and must be released in the Jubilee, because the houses in the cities of the Levites are their possession among the Israelites.

34 But the open pastureland around their cities may not be sold, for this is their permanent possession.

35 Now if your countryman becomes destitute and cannot support himself among you, then you are to help him as you would a foreigner or stranger, so that he can continue to live among you.
