Zephaniah 2:12 - Matthew Poole's English Annotations on the Holy Bible

The prophet doth not speak of the African Ethiopians, south of Egypt, but of the Arabian Ethiopians, much nearer to Canaan, whose country was called Cusaea, with the addition Ethiopia Cusaea. See Habakkuk 3:7. Ye shall be slain, punished by war, and your people cut off, by my sword; Nebuchadnezzar and his Chaldeans, called here God's sword, for God employed and prospered them.
