What Does Genesis 14:3 Mean?

All these latter kings joined forces in the Valley of Siddim, which is the Salt Sea. The Valley of Siddim is identified with the Salt Sea (the Dead Sea), placing the battle site in the region of the southern Jordan valley near the cities of the plain. The geography is consistent: the well-watered valley that Lot chose when he saw it as an Eden-like landscape is the same valley where these five kings are now making their military stand against the returning eastern coalition.

The Salt Sea identification serves both geographical and narrative purposes. Geographically, it anchors the battle narrative in a specific, identifiable landscape. Narratively, it reminds the reader of what happened to the cities of the plain: the fertile Jordan valley of Genesis 13 will become the stark shore of the Salt Sea, associated with the catastrophe of Sodom and Gomorrah. The identification "which is the Salt Sea" may reflect the narrator's perspective from after the cities' destruction, noting what the Valley of Siddim later became.

The choice of this valley as the site for military resistance by the five kings is the five kings' best option: home terrain, knowledge of the local landscape, and the defensive advantage of a valley where the pits of bitumen (mentioned in verse 10) might have tactical applications. The positioning of the battle in the landscape where Lot has settled means that whatever happens to the armies fighting there will happen in his vicinity. The conflict is coming to the neighborhood he chose for its fertility and peace.
