Leviticus 25:35-39

³⁵‘Now in case a countryman of yours becomes poor and his means among you falter, then you are to sustain him, like a stranger or a resident, so that he may live with you. ³⁶Do not take any kind of interest from him, but fear your God, so that your countryman may live with you. ³⁷You shall not give him your silver at interest, nor your food for profit. ³⁸I am the Lord your God, who brought you out of the land of Egypt to give you the land of Canaan, and to be your God.

³⁹‘Now if a countryman of yours becomes so poor with regard to you that he sells himself to you, you shall not subject him to a slave’s service.
