Jews, Idumaeans and Ancient Arabs
His book deals with two major subjects: first, the Idumeans Judaizing, located in Idumea land and the Yturs in the Galilee and their integrating in the Jewish society. The Judaizing action describe in the Hellenistic Historiography as an act of compelling by the Hasmonean, in order to abase their name. Kasher shows that the judaising conducted out of good will and cooperation of the nations who judaized with the Hasmonean. He examines the consequences of the Hellenistic influence in the Idumean society, and its implications on their relations with the neighbor Jewish nation, even though in the Bible the Idumean accused in co-operation with Babylon power and the ruin of Jerusalem and the temple in the year 586 BCE. The second part of the book deals with the Nabataeans relations with the Jews from 332 BCE to 70 AD. The relations start with great friendship in the beginning of the Hashmonean period and ends in the Alexander Jannaeus wars and the Roman rule. It is a pioneering monographic research, that was held in the first time by Aryeh Kasher. till his research historians used to study specially the Jewish People and the regime that conquer the country and hardly look for the non Jewish Israel country inhabitants. This because we hardly have national history papers of this nations authors, the archeological finding about them is scarse and the majority of the knowledge we have is from Josephus, who describe them through their relations with the Jewish people.
