A Kushite is someone descended from Ham, one of the sons of Noah. Kush was the grandson of Noah. The word is sometimes associated with the peoples in the Horn of Africa. Kush, however, is an ancient country in the middle Nile Valley. Pharao Thutmosis I is known to have waged war against it around 1525 b.C..
Numbers (Am. St.) 12:1 tells us: Then Miriam and Aaron spoke against Moses because of the Cushite woman he had married (for he had married an Ethiopian woman).
