Ham

Concise Bible Dictionary:

4. The Simeonites in searching for pasture for their flocks in the South came to a place where they of Ham had dwelt of old (1 Chron. 4:4040And they found fat pasture and good, and the land was wide, and quiet, and peaceable; for they of Ham had dwelt there of old. (1 Chronicles 4:40)). Some suppose these to have been a colony from Egypt; others judge them to have been Canaanitish nomads.
