Leviticus 25:35-43

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.
