Parashas Masei · Passuk 35:22 · TT note 3
Chabad.org — English translation + Rashi
Torah Temimah points to Makkos 7b (TT note on “הֲדָפוֹ אוֹ הִשְׁלִיךְ עָלָיו”).
English: “He pushed him or threw something upon him” — “pushed him” means he shoved him with his body; “or threw something upon him” brings in [the case of] a descent that is needed for an ascent [e.g., descending a ladder while carrying a load].
Scope of unintentional acts that still trigger exile.
Bodily push and accidental drops during necessary activity both fall under the unintentional-homicide verse and require exile.
