Leviticus 25:30-39

³⁰And if it be not ransomed until there be completed of its time a full year, the house which is in the walled city shall be surely confirmed to him that bought it, throughout his generations; and it shall not go out in the release.

³¹But the houses in the villages which have not a wall round about them, shall be reckoned as the fields of the country: they shall always be redeemable, and they shall go out in the release.

³²And the cities of the Levites, the houses of the cities in their possession, shall be always redeemable to the Levites.

³³And if anyone shall redeem a house of the Levites, then shall their sale of the houses of their possession go out in the release; because the houses of the cities of the Levites are their possession in the midst of the children of Israel.

³⁴And the lands set apart for their cities shall not be sold, because this is their perpetual possession.

³⁵And if thy brother who is with thee become poor, and he fail in resources with thee, thou shalt help him as a stranger and a sojourner, and thy brother shall live with thee.

³⁶Thou shalt not receive from him interest, nor increase: and thou shalt fear thy God: I am the Lord: and thy brother shall live with thee.

³⁷Thou shalt not lend thy money to him at interest, and thou shalt not lend thy meat to him to be returned with increase.

³⁸I am the Lord your God, who brought you out of the land of Egypt, to give you the land of Canaan, so as to be your God.

³⁹And if thy brother by thee be lowered, and be sold to thee, he shall not serve thee with the servitude of a slave.
