Abram heads north with his caravan. It is noted at this time that Abram is rich in cattle, silver and gold. Obviously not a poor traveler or a starving wanderer… so just what was this “drought” he was fleeing from? Was it a drought not of weather but of another kind?
They flee to Egypt to avoid the drought, get thrown out, and then return to the land of the drought. Anyways, Abram ends up back where built the altar to Jehovah at Beth-El.
In a story rife with anthropological meaning, two pastoral families run out of land to tend to their herds and flocks of “great substance” (again, drought?) so they conflict, and come to terms with each other since they are kin. Also the author felt it was important to note that the Canaanite and the Perizzite dwelt in the land (we know the genealogy of the Canaanites but not the Perizzites.)
Lot chose the Plain of the Jordan and journeyed east (there it is again) and “moved his tent” (which I’m going to assume is a euphemism for his collective) as far as Sodom. Also of note, Lot saw that the Plain of the Jordan was “well watered”, so either the drought was over or, again, we are talking about a drought of another kind. Abram stayed in the land of Canaan.
Genesis 13:13 – Now the men of Sodom were wicked and sinners against Jehovah exceedingly.
We are given insight into the people of Sodom: they were wicked, however they also answered to Jehovah. This is the first mention of another group that fell under Jehovah’s tutelage and also the first of a people considered wicked and sinners.
It wasn’t until Lot left Abram that Jehovah spoke to Abram, hinting to the future of his lineage:
13:14 – (Jehovah to Abram)… lift up now thine eyes, and look from the place where thou art, northward and southward and eastward and westward: for all the land which thou seest, to thee I will give it, and to thy seed for every. And I will make thy see as the dust of the earth: so that if a man can number the dust of the earth, then may thy seed also be numbered.
Abram “moved his tent” aka his collective and moved to the aforementioned (somewhat) oaks of Mamre which we now find out are in Hebron, where Abram builds another altar for Jehovah.
