Leviticus 25:42-46

MKJV(i) 42 For they are My servants, whom I brought forth out of the land of Egypt. They shall not be sold as a slave. 43 You shall not rule over him with rigor, but shall fear your God. 44 Both your male slaves, and your female slaves whom you shall have, shall be of the nations that are all around you. You shall buy male slaves and female slaves from them. 45 And also you may buy of the sons of the tenants who are staying with you; and from their families that are with you, whom they fathered in your land. And they shall be your possession. 46 And you shall take them as an inheritance for your sons after you, to hold for a possession; you may lay service on them forever. But you shall not rule over your brothers, the sons of Israel, over one another, with harshness.
