An affluent of the Euphrates, joining that river about 35° N. It marks one of the districts to which the Israelites were carried captive (2 Kings 17:6; 2 Kings 18:11; 1 Chron. 5:26). It is now called Khabour. The name of the Habor has been found on some of the ancient Assyrian monuments. In ancient histories it has borne the names of Aborrhas, Aburas, Abora and Chaboras.
