Easton's Bible Dictionary (1897)
The height of Mizpeh or of the watch-tower (Josh. 13:26), a place mentioned as one of the limits of Gad. There were two Mizpehs on the east of the Jordan. This was the Mizpeh where Jacob and Laban made a covenant, “Mizpeh of Gilead,” called also Galeed and Jegar-sahadutha. It has been identified with the modern es-Salt, where the roads from Jericho and from Shechem to Damascus unite, about 25 miles east of the Jordan and 13 south of the
Jabbok.
