“from Edom.” The Hebrew text reads “Aram” (Syria), but this seems to be a corruption of the Hebrew because Syria is far north of the area. The Septuagint and Vulgate read “Edom.” Also, Jehosaphat named the enemies including “Mount Seir,” which is Edom, and he did not mention Syria (2 Chron. 20:10). It is likely that the army from Edom crossed the Dead Sea at the jut of land that extends most of the way across the Dead Sea.
“En-gedi.” “En-gedi” means “the spring of the wild goats,” and it is located on the west side of the Dead Sea. It is a beautiful oasis, with plenty of water, and David hid out there from Saul (1 Sam. 23:29; 24:1). It is specifically mentioned as part of the global restoration of the earth in the Millennial Kingdom, when the Dead Sea is healed (Ezek. 47:10).
