JAZER.—An Amorite town N. of Heshbon, taken by Israel (Num_21:32), allotted to Gad (Jos_13:25 etc.), and fortified by it (Num_32:35). It lay in a district rich in vines (Isa_16:8 etc., Jer_48:32). It is probably represented by Khirbet Sâr, about 7 miles W. of ‘Ammân, a mile E. of Wâdy Sîr. Judas Maccabæus took the city, which was then in the hands of the Ammonites (1Ma_5:9; Jos. [Note: Josephus.] Ant. XII. viii. 1).
