NASBAS. Apparently the nephew of Achiacharus, who was the nephew of Tobit ( Tob 11:18 ). He came with Achiacharus to the wedding of Tobias. About his identity there is some little uncertainty. The Vulgate speaks of him as brother of Achiacharus, while others have regarded the two as identical. It has been suggested also that he is the same as Aman or Nadan, the ward of Achiacharus ( Tob 14:10 ), in which case the uncle adopted the nephew and brought him up as his son.
