Parashas Masei · Passuk 35:23 · TT note 3
Chabad.org — English translation + Rashi
Torah Temimah points to Makkos 7b (TT note on “וַיַּפֵּל עָלָיו”).
English: “And it fell upon him” — only when it falls in the manner of a fall [i.e., from above downward].
Limitation of the verse to downward falls, not lateral or upward projections.
The unintentional-homicide provision covers only objects that fall downward onto the victim, not projectiles launched sideways or upward.
