ACCAD, a city built by Nimrod, Gen. x. 10. The Septuagint writes it Arcad; the Syriac Achar. Ephraim the Syrian says, Achar is the city Nisibis ; and in this he is followed by Jerome and Abulpharagius. The Targums of Jerusalem and Jonathan read Nesibin. The antiquity of this city is unquestionable.
