TT #382 · Parashas Shoftim · Seventh Aliyah · Passuk 21:07
And they shall declare and say: Our hands did not shed this blood, and our eyes did not see.
Torah Temimah points to Sotah 47a.
TT lemma: וְעֵינֵינוּ לֹא רָאוּ.
English: ‘And our eyes did not see’ – that we did not dismiss him without food and without escort.
Derash unpacking the declaration (Bavli) — the blood-guilt that the city might bear is the failure to care for the traveler.
By saying ‘our eyes did not see’ the elders affirm that they did not allow a traveler to leave their city without provisions and an escort.
