A town in western Judah in the lowlands, mentioned in connection with Mareshah and Keilah as one of the cities allotted to Judah (Joshua 15:44 ), and in Micah (1:14), where it suggests play upon its meaning, "deceptive" or "failing," possibly the place having received its name from a winter spring or brook, which failed in summer. It is also called Chezib (kezibh (Genesis 38:5 )), where Judah was at the time of the birth of his son Shelah. In 1 Chronicles 4:22 it is called Cozeba, the King James Version "Chozeba" (kozebha'), clearly seen to be the same as Achzib, from the places with which it is grouped.
