‘The names of Ham’s sons are not preserved even in corrupted form in modern times. The sons of Ham were Cush, Mizraim, Phut, and Canaan, but not one of these is held today by any living representatives in any recognisable form whatever. Cush subsequently became identified with Ethiopia, Mizraim with Egypt, Phut with Libya, and Canaan with Palestine, but the old names pass completely out of use’ (Custance). The Septuagint calls the Cushites, Aethiopes, which means ‘a black countenance’, from which comes the name Ethiopians, but the modern-day Ethiopians are to the south of ancient Cush. Evidently, the descendants of Cush did not only go to the ancient area of Nubia (modern Ethiopia) but also east to Nineveh.
Seba is mentioned along with Sheba and Tarshish and the isles in Psalm 72:10, in a prophecy about the coming of Gentiles to Christ. This is very interesting because descendants of Japheth and of Ham are mentioned in the same breath. Isaiah also prophesies the conversion of those from Egypt and Cush (Isaiah 11:11). The curse on Ham did not include all his children. Seba is associated with the ancient city of Meroe in upper Egypt, Havilah with certain Arabic tribes, Sabtah with a city in Arabia, Raamah with the tribe of the Sabaeans in southwest Arabia, and Sabtecha a branch of the Ethiopians furthest to the east. Sheba is the land referred to frequently in the Bible, and Dedan is another part of Arabia (Leupold, Exposition of Genesis).
