Genesis 15:19

The Kenites. The ten tribes listed do not include all the Canaanites. The number is perhaps symbolic of universality. The Kenites were in the mountainous parts of southwestern Palestine, near the Amalekites (Num. 24:20, 21; 1 Sam. 15:6; etc.). Their origin is not certain. At some time they may have intermarried with the Midianites, for Hobab, Moses’ brother-in-law, is called a Kenite (Judges 1:16; 4:11) and also a Midianite (Num. 10:29). They may have been a subfamily of the Midianites.

The Kenizzites. Not yet identified. Some think them to have been descendants of Esau’s grandson Kenaz (Gen. 36:15). If this be so, their mention here as a tribe would of necessity be prophetic, for Esau, a grandson of Abram, was not yet born. This suggestion hardly seems acceptable.

The Kadmonites. Not mentioned elsewhere. Their origin cannot be determined. Their name, meaning “easterners,” points to the eastern regions of Canaan as their abode.
