Leviticus 25:32-39

³²And respecting the cities of the Levites, the houses of the cities of their possession, a perpetual right of redemption shall belong to the Levites.

³³And if a man of the Levites redeem something: then shall the house that was sold, and the city of his possession, become freed in the jubilee; for the houses of the cities of the Levites are their possession among the children of Israel.

³⁴And a field of the suburbs of their cities shall not be sold; for a perpetual possession is it unto them.

³⁵And if thy brother become poor, and fall in decay with thee: then shalt thou assist him, yea a stranger, or a sojourner, that he may live with thee.

³⁶Thou shalt not take of him any usury or increase; but thou shalt be afraid of thy God: that thy brother may live with thee.

³⁷Thy money shalt thou not give him upon usury, nor lend him thy victuals for increase.

³⁸I am the Lord your God, who have brought you forth out of the land of Egypt, to give unto you the land of Canaan, to be unto you a God.

³⁹And if thy brother become poor near thee, and be sold unto thee: thou shalt not compel him to work as a bond-servant.
