Leviticus 25:44-46

Amplified Bible, Classic Edition

⁴⁴ As for your bondmen and your bondmaids whom you may have, they shall be from the nations round about you, of whom you may buy bondmen and bondmaids.

⁴⁵ Moreover, of the children of the strangers who sojourn among you, of them you may buy and of their families that are with you which they have begotten in your land, and they shall be your possession.

⁴⁶ And you shall make them an inheritance for your children after you, to hold for a possession; of them shall you take your bondmen always, but over your brethren the Israelites you shall not rule one over another with harshness (severity, oppression).
