Leviticus 25:39-46

39‘1If a 2countryman 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. 40He shall be with you as a hired man, as 3if he were a sojourner; he shall serve with you until the year of jubilee. 41He shall then go out from you, he and his sons with him, and shall go back to his family, that he may return to the property of his forefathers. 42For they are My servants whom I brought out from the land of Egypt; they are not to be sold in a slave sale. 434You shall not rule over him with severity, but are to revere your God. 44As for your male and female slaves whom you may have--you may acquire male and female slaves from the pagan nations that are around you. 45Then, too, it is out of the sons of the sojourners who live as aliens among you that you may gain acquisition, and out of their families who are with you, whom they will have 5produced in your land; they also may become your possession. 46You may even bequeath them to your sons after you, to receive as a possession; you can use them as permanent slaves. 6But in respect to your 7countrymen, the sons of Israel, you shall not rule with severity over one another.
