פירוש על בראשית 13:12

ויאהל means he pitched tents for his shepherds and cattle עד סדום throughout the whole district extending AS FAR AS SODOM.

ABRAM DWELT IN THE LAND OF CANAAN. The meaning thereof is that he dwelt in the remainder of the entire land of Canaan; he did not stay in one place but abode in the entire land of Canaan while Lot settled in one place thereof, namely, the cities of the Plain, for the cities of the Plain are part of the land of Canaan. The meaning of [the plural “cities” in the expression, and Lot dwelt in] the cities of the Plain, is that he dwelt for a time in this city and a time in the other on account of his many cattle. This is the reason that the verse says, So Lot chose him all the plain of the Jordan;¹⁰⁶Verse 11 here. he made a condition with Abram that he [Abram] should not come into the entire Plain.

אברם ישב בארץ כנען, even though the city of Sodom and its satellite towns are on the border of the land of Canaan, the people living in those cities at that time, were not Canaanites. It was therefore in order for the Torah to write that Avram- as opposed to Lot- settled in the land of Canaan. He settled in the part of the land inhabited by Canaanites. They were not as evil as the Sodomites. Avram did not move close to the boundary of Sodom at all.
