Cushite in the Bible Encyclopedia - ISBE
kush'-it: Whereas kushi, is elsewhere rendered Ethiopian, in 2
Sam 18:21-32 it is rendered Cushite in the Revised Version
(British and American) (see CUSHI and compare CUSHITE WOMAN).
Its plural, which occurs in Zephaniah, Daniel and 2
Chronicles, also in the form kushiyim, in Amos, is uniformly
translated Ethiopians, following Septuagint. The other Old
Testament books use simply kush, for people as well as land.
