Easton's Bible Dictionary

Zoar - 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.
