דברי הימים א, פרק ד׳, פסוק ל״ט

A growing need for grazing land often forces communities to uproot and embark on long journeys. Driven by this exact necessity to find fresh pasture for their flocks, families traveled great distances until they arrived at the entrance of a city named Gedor [רש״י, מצודת דוד, רלב״ג].

The decision to target this specific region was based on the unique nature of the land and the people living there. Historically settled by the descendants of Ham, the area was known for its profound peace. The local inhabitants lived entirely free from the fear of foreign invasions or internal uprisings. Because they felt so secure, they maintained absolutely no military defenses. This complete lack of preparation made the fertile region an easy and attractive destination for the wandering shepherds in need of land [מלבי״ם].
