Arbo'nai (Gr. Abronas, Α᾿βρωνᾶς v. r. Α᾿βρωναϊv, see Fritzsche, Comment. in loc.), a stream, as it would seem, in Mesopotamia, having several considerable cities on its banks which were destroyed by Holofernes (Judith 2:24). Some regard it as being the same with the Habor (q.v.) or Chaboras of Scripture (2Ki 17:16). But it is probably a false rendering of a bungling translator for the original Hebrews בּעֵבֶר הִנָּהָר, beyond the river, i, e. Euphrates (see Movers, in the Bonner Zeitschr. 13:38).
