Parashas Masei · Passuk 35:26 · TT note 1
Chabad.org — English translation + Rashi
Torah Temimah points to Makkos 12a (TT note on “וְאִם יָצֹא יֵצֵא”).
English: Why does Scripture say “goes out, goes out”? To teach: if he left intentionally he is killed; if unintentionally he goes into exile [again].
Double language distinguishing intentional vs unintentional exit from the city of refuge.
Leaving the city of refuge deliberately makes the killer liable to death at the avenger’s hand; an accidental exit merely restarts the exile obligation.
