Achzib, in the tribe of Asher nominally, but almost always in the possession of the Phoenicians; being, indeed, one of the places from which the Israelites were unable to expel the former inhabitants (Judges 1:31). In the Talmud it is called Chezib. The Greeks called it Ecdippa; and it still survives under the name of Zib. It is upon the Mediterranean coast, about ten miles north of Acre. It stands on an ascent close by the sea-side, and is described as a small place, with a few palm-trees rising above the dwellings.
Achzib, in the tribe of Judah (Joshua 15:44; Micah 1:14), of which there is no historical mention, but, from its place in the catalogue, it appears to have been in the middle part of the western border-land of the tribe, towards the Philistines. This is very possibly the Chezib of Genesis 38:5.
