It is sometimes helpful in reading the text to find a Bible Atlas or other resource and try to plot out the locations of the story. In Genesis 14 there are 11 kings, about half a dozen battles, and a number of geographic details that mapping clarifies. It is nice to fond one that was done by an expert. But scratching out your own map is an exercise in paying attention to the details. I cross referenced my two Biblical Atlases (Oxford Bible Atlas and New Bible Atlas) a Study bible (which often have maps in the back) and commentaries.
Above is my work. It got me to thinking about getting goat-herd soldiers to take on a larger force of battle tested soldiers lead by a man with a vision from God.
