Albert Barnes Commentary Joshua 19:25-26

"And their border was Helkath, and Hali, and Beten, and Achshaph, and Allammelech, and Amad, and Mishal; and it reached to Carmel westward, and to Shihor-libnath;" — Joshua 19:25-26 (ASV)

Helkath, a Levitical town (Joshua 21:31), is probably Yerka, a village about seven or eight miles northwest of Acre, in a wadi of the same name. Alammelech was in the “Wady Melik,” which joins the Kishon from the northeast, not far from the sea.

Shihor-libnath—that is, “black-white.” The two words are now generally admitted to be the name of a river, probably the modern “Nahr Zerka,” or Blue River, which reaches the sea about 8 miles south of Dor, and whose name has a correspondence both to black and white. Possibly we have in the occurrence of the term Shihor here a trace of the contact, which was close and continuous in ancient times, between Phoenicia and Egypt (Joshua 13:3). Cabul (Joshua 19:27) still retains its ancient name; it lies between four and five miles west of Jotapata and about ten miles southeast of Acre.
