THERAS

the'-ras (Thera): The river by which the company assembled in preparation for the march to Jerusalem under Ezra (1 Esdras 8:41,61). In Ezra 8:21,31 the name of the river is Ahava. Possibly the place is represented by the modern Hit on the Euphrates; but no certain identification is possible.
