Leviticus 25:29-43

29And if a man sell a dwelling-house in a walled city, then he may redeem it within a whole year after it is sold; for a full year shall he have the right of redemption. 30And if it be not redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him that bought it, throughout his generations: it shall not go out in the jubilee. 31But the houses of the villages which have no wall round about them shall be reckoned with the fields of the country: they may be redeemed, and they shall go out in the jubilee. 32Nevertheless the cities of the Levites, the houses of the cities of their possession, may the Levites redeem at any time. 33And if one of the Levites redeem, then the house that was sold, and the city of his possession, shall go out in the jubilee; for the houses of the cities of the Levites are their possession among the children of Israel. 34But the field of the suburbs of their cities may not be sold; for it is their perpetual possession.

35And if thy brother be waxed poor, and his hand fail with thee; then thou shalt uphold him: as a stranger and a sojourner shall he live with thee. 36Take thou no interest of him or increase, but fear thy God; that thy brother may live with thee. 37Thou shalt not give him thy money upon interest, nor give him thy victuals for increase. 38I am Jehovah your God, who brought you forth out of the land of Egypt, to give you the land of Canaan, and to be your God.

39And if thy brother be waxed poor with thee, and sell himself unto thee; thou shalt not make him to serve as a bondservant. 40As a hired servant, and as a sojourner, he shall be with thee; he shall serve with thee unto the year of jubilee: 41then shall he go out from thee, he and his children with him, and shall return unto his own family, and unto the possession of his fathers shall he return. 42For they are my servants, whom I brought forth out of the land of Egypt: they shall not be sold as bondmen. 43Thou shalt not rule over him with rigor, but shalt fear thy God.
