Cush or Kush, according to the Hebrew Bible, was the oldest son of Ham and a grandson of Noah. He was the brother of Mizraim, Phut, and Canaan. Cush was the father of Nimrod.
A page from Elia Levita's 16th-century Yiddish–Hebrew–Latin–German dictionary contains a list of nations, including the word "כושי" Cushite or Cushi, translated to Latin as "Aethiops" and into German as "Mor".
Ham, according to the Table of Nations in the Book of Genesis, was the second son of Noah and the father of Cush, Mizraim, Phut and Canaan.
