Dug over, a town in the Shephelah or low hills of Judah (Josh. 15:35), where the five confederated Amoritish kings were
defeated by Joshua and their army destroyed by a hailstrom
(10:10, 11). It was one of the places re-occupied by the Jews on
their return from the Captivity (Neh. 11:30).
Smith's Dictionary
(dugover), a town of Judah, with dependent villages, lying in the Shefelah or rich agricultural plain. It is most clearly defined as being near Shochoh, (1 Samuel 17:1) but its position has not yet been recognized.
