What does the Torah mean when it writes that "Yakov lifted his feet"?
Rashi and Targum Yonasan: Following the good news that he had just received, his heart lifted his feet as it were, and walking became effortless.
Rashbam: Following the promises from Hashem, he proceeded on his journey happy and fleet of foot.
Seforno: As opposed to someone who departs from a place because he has nowhere to stay, in which case his feet carry him, 1 when someone leaves with the intention of reaching a specific destination, he carries his feet.
Oznayim la'Torah: The Midrash explains how David would plan to go to a certain destination, but his feet would automatically take him to the Batei Kenesiyos and the Batei Midrashos. Certainly, Yakov (the prince of Torah) would either have done likewise or he would have opted to remain in the vicinity of the Beis-Hamikdash. However, hiw father had instructed him to go to Charan, so he lifted his feet and went there.
Why did he go to the land of Bnei Kedem?
Rashbam: The Pasuk is referring to Padan Aram which is east of Eretz Yisrael. 1
Moshav Zekenim: He went to learn from Shem and Ever. 2
