HYDASPES.A river mentioned in Jdt_1:6 as on the Medo-Babylonian frontier. The name is probably the result of a confusion with the well-known Hydaspes in India (now the Jatam). In view of the mythical character of the Book of Judith, speculation as to the identity of this river is likely to remain fruitless. However, there may be a suggestion in the fact that the Syr. version reads Ulai (wh. see).

hı̄-das?pēz (Ὑδάσπης, Hudáspēs): A river mentioned in Judith 1:6 in connection with the Euphrates and Tigris, but otherwise unknown. It is possible there may be a confusion with the Hydaspes of India. Some have conjectured an identity with the Choaspes.

Hydaspes
( ῾Υδάσπης), a river noticed in Judith 1, 6, in connection with the Euphrates and Tigris, mentioned by Arrian (Ind. 4) and Strabo (15, 697), which flowed westwards into the Indus, and is now called Jelam (Rawlinson, Herod. i, 558). The well-known Hydaspes of India is too remote to accord with the other localities noticed in the context. We may perhaps identify it with the Choaspes or Euloeus of Susiana, which was called Hydaspes by the Romans (Voss, ad Justin. ii, 14).
