(Heb. Chelkath', חֶלְקִת ,  Joshua 19:25, but חֶלְקָת , even without pause- accent,  Joshua 21:31;" construct" of, חֶלְקָה , Smoothness, as in  Genesis 27:16, Or Potion, as in  Genesis 33:19, etc.; Sept. Χελκάθ ), a town of Asher, on the eastern border, mentioned as the starting-point in the direction (apparently southward) to Achshaph ( Joshua 19:25); assigned as one of the Levitical cities ( Joshua 21:31). In  1 Chronicles 6:75, it appears to be erroneously written HUKOK. (See Hukkoe). p the Onomnasticon it is simply mentioned by Eusebius as Eoiri, by Jerome as Elcath; but neither seems to have known it. De Saulcy inclines to identify it with a village called Kirkeh, which he reports not far southeast of Akka (Narrative, 1, 68); and Schwarz (Palestine, p. 191) thinks it is the modern Yerka, about seven miles north-east of Akka; but neither of these positions is in the neighborhood indicated by the text, which rather requires a locality nearer the north-eastern angle of the tribe, not unlikely at the ruined village Ukrith, about twelve miles S.E. of Tyre, as proposed by Van de Velde (Memoir, p. 320). (See Helkath- Hazzuarim).
