EBAL (ē'băl, Heb. ‘êvāl, meaning uncertain)
A son of Shobal (Gen.36.23; 1Chr.1.40).A mountain 3,077 feet (962 m.) high, one of the highest points in the land of Samaria. It stood opposite Mount Gerizim, across a valley through which ran an important route of travel. At its foot was Jacob’s well (see John.4.20: “on this mountain”), and the city of Shechem was located nearby. When the Israelites first entered the land, Moses commanded them to erect on Mount Ebal a monument of stones on which the law was inscribed and a stone altar for burnt offerings and peace offerings. The law, with its blessings and curses, was recited by the people antiphonally, the blessings from Mount Gerizim and the curses from Mount Ebal (Deut.27.4-Deut.27.26). Joshua renewed this procedure after the conquest of Ai (Josh.8.30-Josh.8.35). The central location of this mountain and its height made it valuable for military purposes. A ruined fortress is still visible on its summit.In KJV one of the sons of Joktan; rendered Obal in NIV (1Chr.1.22).
