اَلْعَدَد 35:15

لِبَنِي إِسْرَائِيلَ وَلِلْغَرِيبِ وَلِلْمُسْتَوْطِنِ فِي وَسَطِهِمْ تَكُونُ هَذِهِ ٱلسِّتُّ ٱلْمُدُنِ لِلْمَلْجَإِ، لِكَيْ يَهْرُبَ إِلَيْهَا كُلُّ مَنْ قَتَلَ نَفْسًا سَهْوًا.

These six cities shall be a refuge, both for the children of Israel, and for the stranger, and for the sojourner among them: that every one that killeth any person unawares may flee thither.
