But if the slayer shall at any time come without the border of
the city of his refuge
Which seems to be the three thousand cubits assigned to every city of the Levites, and so to the cities of refuge; and which, according to the Jewish writers, were a refuge, as the city itself; and it is said F24,
``he, that kills a man there, is killed for him, but though the border is a refuge, the slayer does not dwell in it, as it is said. ( Numbers 35:25 ) , "he shall abide in it", but not in its borders:''whither he was fled;
on account of manslaughter.
