Izates

Izates II (Ἰζάτης), son of Monobaz (Μονόβαζος), or Izates bar Monobaz (also known as Izaates, Persian: ایزد‎‎ or Hebrew: זוטוס בן מונבז‎‎) (ca. 1-55 CE). Izates, or Izas as Josephus Flavius sometimes calls him, was a king of the Parthian client kingdom of Adiabene who became a proselyte to Judaism. He was the son of Queen Helena of Adiabene and King Monobazus I of Adiabene. Queen Helena was also said to be the wife of King Abgarus of Edessa and thus the queen of Edessa too. This implies that Izates II was the king of Edessa, as well as of Adiabene, and therefore cognate with either Manu V or Manu VI. Moses of Chorene confirms that this Queen Helena of Edessa was also the queen of Adiabene when he says:

During his youth Izates was sent by his father to the court of King Abinergaos I of Characene in Charax Spasinu. While in Charax Izates became acquainted with a Jewish merchant named Ananias, who familiarized him with the tenets of the Jewish religion, in which he became deeply interested. Izates married King Abinergaos' daughter Symacho who had been converted to Judaism through the efforts of Ananias. His mother had been previously won over to Judaism without his knowledge. On returning home and ascending the throne on the death of his father (c. 31 CE), Izates discovered the conversion of his mother; and he himself intended to adopt Judaism, and even to submit to circumcision. He was, however, dissuaded from this step both by his teacher Ananias and by his mother, but was ultimately persuaded thereto by another Jew, Eleazar.
