 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."
