בראשית, פרק כ״ו, פסוק י״ז

Faced with mounting tension, Isaac chooses the path of peace and avoids open conflict, demonstrating absolute loyalty to God's command. Even though he possessed great power, a large number of servants, and the physical strength to fight the Philistine king, he decides to leave his home without a struggle. This choice stems directly from God's instruction for him to live in the land as a temporary resident and stranger [מלבי״ם]. At the same time, Isaac is careful not to leave the Philistine territory completely, wanting to fulfill God's command to remain within the borders of the land. This creates a complex reality. God promises Isaac all the lands, yet does not allow him to live in them peacefully like an ordinary person. This paradox is a divine test designed to evaluate his faith and ensure he does not question God's ways, much like the trials experienced by his father Abraham [אור החיים].

During this journey, Isaac travels south [ביאור שטיינזלץ] and settles in a valley. Geographically, this term simply describes a lowland area, and a place can be called a valley even if it contains no flowing water at all [רד״ק, ביאור יש״ר]. Regarding the exact location of this valley, the primary approach among commentators is that it was situated a significant distance away from the city of Gerar itself. If the area had been close to the capital, it would still be considered part of the city's territory, and the king would have expelled him from there as well [רש״י, מזרחי, שפתי חכמים, משכיל לדוד, דברי דוד]. The distant location still carried the name Gerar either because the valley physically extended from the city area out toward another land [רמב״ן, מזרחי], or because there was another small town in that valley that shared the same name [רד״ק].

Upon arriving, Isaac establishes his new base with a clear distinction between his general camp and his personal home. He places his animals, business operations, and vast property in one area, while setting up his personal tent nearby. Moving out of the city and keeping his immense wealth away from the eyes of the Philistine officials is a calculated choice. This separation effectively calms their jealousy and allows him to maintain his household in peace [העמק דבר].
