Nahum, or Nehunyon, was a Jewish exilarch of the 2nd century AD, [1] according to the Seder Olam Zutta , residing within the Parthian Empire. [2] He is believed to be one of the oldest identifiable members of the house of the exilarch [3] in Babylonia, as no explicit mention of one is noted before his tenure. Very little is known about him or the nature of the office that he served during his lifetime. [4] He was allegedly succeeded as exilarch by his brother Johanan. [5]
