Komentaryo sa Genesis 13:3: Rashi, Ibn Ezra, Sforno & Radak

וילך למסעיו AND HE WENT ON HIS JOURNEYS — When he returned from Egypt to the land of Canaan he went and lodged in the same inns as he had stayed when he travelled to Egypt. This teaches you good manners: that one should not change his inn (Arachin 16b); (where the reason is given that one who does this constantly brings discredit on himself and on others). Another interpretation: on his return he paid the debts he had previously incurred (Genesis Rabbah 41:3). (In both these comments emphasis is placed on “his” — he went on his journeys i.e. the routes he had taken before.)

For his journey. That he journeyed a great distance when he returned from the southern edge to Beit El which is in the north, and came to the place of the altar to thank God that he made his journey safely.

וילך למסעיו, this is why he traveled on his routes, i.e. the routes all the shepherds took when journeying in that direction.

מנגב FROM THE SOUTH — the land of Egypt lies to the South of the land of Canaan.
