The term "tall and smooth-skinned people" is primarily derived from the biblical description found in the book of Isaiah. This phrase is often associated with the Cushites, an ancient people who lived in the region south of Egypt, corresponding to modern-day Sudan and Ethiopia. The Cushites are mentioned several times in the Bible, and their physical characteristics are highlighted in certain passages.

Biblical References:
