Chivi in Hebrew. They lived in the central part of the Holy Land near Shechem (Genesis 34:2). They also lived in Gibeon, and as nethinim survived the conquest of the Holy Land (Joshua 9:3,7, 11:19). They lived in the north, near Mount Lebanon, from Hermon to Chamath (Judges 3:3). Some identify them with the people of Tripoli (Targum Yerushalmi). The Midrash apparently notes that they were cave dwellers (Chaldun; Bereshith Rabbah 37). They were also adept at testing soil by taste (Shabbath 85a, but see Tosefoth ad loc. s.v. Chivi). See note on Genesis 36:3.
