Smith's Bible Dictionary
Go'zan. Gozan seems in the Authorized Version of 1 Chronicles 5:26 to be the name of a river, but in 2 Kings 17:6 and 2 Kings 18:11, it is evidently applied, not to a river, but a country.
Gozan was the tract to which the Israelites were carried away captive by Pul, Tiglathpileser and Shalmaneser, or possibly Sargon. It is probably identical with the Gauzanitis of Ptolemy, and it may be regarded as represented by the Mygdonia of other writers. It was the tract watered by the Habor, the modern Khabour, the great Mesopotamian affluent of the Euphrates.
