Commentary for Genesis 12:9

הלוך ונסוע GOING ON MORE AND MORE TOWARDS THE NEGEB — by stages: he stayed here a month or more, then travelled on and pitched his tent in another place. Yet all his journeys were towards the Negeb to proceed to the South of the land of Israel which is the direction where Jerusalem is — which is in the territory of Judah who had their portion in the South of the land of Israel — to Mount Moriah which is his (Judah’s) possession (cf. Genesis Rabbah 39:16).

TOWARDS THE SOUTH. Rabbeinu Shlomo [Rashi] wrote, “To go to the southern part of the land of Israel, which is in the territory of the sons of Judah who took their portion in the south of the land of Israel.” This was also to happen to Abraham’s offspring in the future, as it is said, Judah shall go up⁶⁸Judges 1:2. first.

And Avram journeyed - journeyed from here, and went. Continually traveling - from place to place.
