וְהִקְרִיתֶ֤ם לָכֶם֙ עָרִ֔ים עָרֵ֥י מִקְלָ֖ט תִּהְיֶ֣ינָה לָכֶ֑ם וְנָ֥ס שָׁ֙מָּה֙ רֹצֵ֔חַ מַכֵּה־נֶ֖פֶשׁ בִּשְׁגָגָֽה׃
vous choisirez des villes propres à vous servir de cités d’asile: là se réfugiera le meurtrier, homicide par imprudence.
Makkot
Witnesses testify that this person is subject to exile, we don't say that they [the false witnesses] are exiled in his place, rather they are lashed forty times.
Makkot
From where do we learn this rule [that zomemim aren't liable if the victim had no verdict] by exile? The Torah uses a gezariah shava of Rotzaich Rotzaich
Makkot
[Or] if he was ascending on a ladder and if he fell and killed him, this one is not [liable for] exile. This is the general rule: Anyone on his way down, [that person is liable for] exile. Anyone that is not on his way down, [that person is liable for] exile.
