You may give them as inheritance to your children after you to possess as property. You may enslave them perpetually. However, as for your brothers the Israelites, no man may rule over his brother harshly. ¹

Everyone’s inheritance must be in the place where his lot falls. You must inherit according to your ancestral ¹  tribes.
