In Genesis, Ham is named as the father of Cush.
Genesis 10:6 lists Ham’s sons as Cush, Mizraim, Put, and Canaan. This genealogy appears in the chapter commonly called the Table of Nations, which presents lines of descent from Noah’s sons after the Flood.
The verse is easy to confuse because Canaan is also listed as Ham’s son. Canaan is not the father of Cush in the biblical genealogy; both are presented as sons of Ham. The same chapter continues by naming descendants associated with each family line.
The Table of Nations is a biblical genealogy and ethnographic framework, not a modern population-genetics classification. Names such as Cush and Mizraim are traditionally associated with regions or peoples, but their identifications and historical boundaries are discussed by scholars. The direct answer to the genealogical question remains Ham.
