Kommentar zu Bereschit 11:31

ויצאו אתם AND THEY WENT FORTH WITH THEM — ויצאו אתם Terah and Abram went forth with Lot and Sarai.

AND THEY WENT FORTH WITH THEM FROM UR OF THE CHALDEES. Because Abram was more important than his father and those that followed his counsel and for whose sake they went, Scripture says, And they went forth, [rather than “he went forth”] even though it says at the beginning of the verse, And Terah took. Lot and Sarai, however, went with them to the land of Canaan on account of Abram, for even after Abram separated from his father they went along with him.³⁸²The Tur concludes: “Thus it should have said, ‘and they walked with him,’ that is with Abram. But out of respect to his father, Scripture ascribes it to both of them.”

ללכת ארצה כנען, this land is prepared for enabling its residents to acquire all intellectual advantages, and, as far as G’d is concerned, it is the most preferred of all the countries on earth. We have this on the authority of the Torah itself which says of that land (Deuteronomy 11,12) ארץ אשר ה' אלוקיך דורש אותה תמיד עיני ה' אלוקיך בה מרשית השנה ועד אחרית שנה, “and concerning which G’d enquires constantly, His eyes being trained on it from the beginning of the year until the year’s end.” The climate of the land of Canaan had not been negatively affected by the rains of the deluge, as had the climate of all other parts of the globe. We have this on the authority of Ezekiel 22,24 ארץ לא גשמה ביום זעם, “a land which did not experience rain on the day of the fury.” This may well be the reason why the sages (Baba Batra 58) said that the climate of the land of Israel makes people smarter.
