פירוש על דברי הימים א 19:6

from Aram Naharaim and from Aram-Maacah There were many Arameans, and that is the meaning of Aram-Maacah - the Arameans dwelling in Maacah. Some Arameans dwelt by the Euphrates River, and [likewise] Aram-Zobah; but Aram, without a surname, is the main part of the nation. Similarly, the Ammonites dwelling in Ammon are called Ammonites, but the main part of the nation was in other places, and so, the children of Esau in the land of Seir, but the main part [of the nation] dwelt in Edom.
