Jaazer

He (God) helps, a city of the Amorites on the east of Jordan, and assigned, with neighbouring places in Gilead, to Gad (Num. 32:1, 35; Josh. 13:25). It was allotted to the Merarite Levites (21:39). In David’s time it was occupied by the Hebronites, i.e., the descendants of Kohath (1 Chr. 26:31). It is mentioned in the “burdens” proclaimed over Moab (Isa. 16:8, 9; Jer. 48:32). Its site is marked by the modern ruin called Sar or Seir, about 10 miles west of Amman, and 12 from Heshbon. “The vineyards that once covered the hill-sides are gone; and the wild Bedawin from the eastern desert make cultivation of any kind impossible.”
