The second factor in understanding the geography of the Bible is to note that this small strip of land is the land bridge to the continents of Africa, Europe, and Asia. To control who could travel through a place the size of the state of New Jersey was to control wealth and trade. In the southern reaches of what was first called Canaan, the city of Beersheba was known as an oasis for the nomadic tribes that traveled the desert then and still do today. In fact, the Bedouin of the southern desert today are loyal to the people of Abraham because they believe that he was first a desert nomad. The third factor is to understand the geographic language of the Bible.
Distance is measured by the number of days it took to walk from one place to another.
Abraham's journey to Mount Moriah to sacrifice Isaac was three days, one way. And it is important not to confuse Hollywood with the Bible. The best scholarship today places Sodom and Gomorrah on the opposite side of the Dead Sea, across from Beersheba. Something of a major detour, I think. People are characterized as going down to Jericho and up to Jerusalem.
