Small, a town on the east or south-east of the Dead Sea, to which Lot and his daughters fled from Sodom (Gen. 19:22, 23). It was originally called Bela (14:2, 8). It is referred to by the prophets Isaiah (15:5) and Jeremiah (48:34). Its ruins are still seen at the opening of the ravine of Kerak, the Kir-Moab referred to in 2 Kings 3, the modern Tell esh-Shaghur.
Zoar
“The sun was risen upon the earth when Lot entered into Zoar.” Lot had been told to run for the hills, and he asked instead for a small town nearby: “Oh, let me escape thither.” It was granted, and “the name of the city was called Zoar.” Yet Lot soon left, since “he feared to dwell in Zoar,” and he settled in a cave with his two daughters. The name appears twice more, once at the edge of what Moses saw from Nebo, and once in a lament over Moab’s refugees.
