Hydaspes

HYDASPES hī dăs’ pez (LXX ̔Υδάσπης). A river mentioned in the Apoc. (Judg 1:6), but not in the canonical Heb. OT.

In Judith 1:6 the river Hydaspes is mentioned with the Euphrates and Tigris Rivers and with Elymais (cf. Elam), thus seeming to be located in a region of the Tigris and Euphrates near the Persian Gulf. Syriac has Ulai (cf. Dan 8:2, where the Ulai is in Elam).

International Standard Bible Encyclopedia (1915)

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.
