דברי הימים א, פרק ד׳, פסוק מ׳

The search for new territory eventually led to the discovery of a vast, fertile, and peaceful region. This spacious land was home to long-time residents who lived in a state of absolute security. These inhabitants were descendants of Ham who had settled in the area during ancient times. Because their ownership of the land had gone unchallenged for generations, they had never experienced the threat of conflict. They did not expect anyone to bring them harm, and they were not warriors by nature [ביאור שטיינזלץ].

This deep, unbroken peace shaped their entire way of life, but the primary approach among commentators is that this absolute security is exactly what led to their downfall. Entirely unaccustomed to the dangers of war, the inhabitants lived without fear and failed to maintain any basic defenses. They did not stand guard over their territory, nor did they bother to form defensive alliances with neighboring groups who might come to their aid in a time of crisis. This extreme complacency left them completely vulnerable to a sudden attack. Their situation closely mirrored that of the ancient city of Laish, whose people were easily conquered simply because they lived quietly and securely without any outside support [רש״י].
