Mambo ya Walawi 25 : 46 Leviticus chapter 25 verse 46

Nanyi mtawafanya kuwa urithi kwa watoto wenu baada yenu, wawe milki yao; siku zote mtatwaa watumwa wenu katika hao; lakini msitawale kwa nguvu juu ya ndugu zenu, hao wana wa Israeli, wenyewe kwa wenyewe.
soma Mlango wa 25

You may make them an inheritance for your children after you, to hold for a possession; of them may you take your slaves forever: but over your brothers the children of Israel you shall not rule, one over another, with harshness.
