“Ethiopia” From Boyd’s Bible Dictionary:
(burnt faces). Greek and Roman for Hebrew “Cush.” The unbounded country south of Egypt (Ezek. 29:10); settled by Hamites (Gen. 10:6); merchants (Isa. 45:14; Jer. 13:23; Job 28:19); wealthy (Acts 8:27-37); strongly military (2 Chron. 12:3; 14:9-12; 2 Kings 17:4).
“Cush” From Concise Bible Dictionary:
1. Eldest son of Ham and grandson of Noah (Gen. 10:6-8; 1 Chron. 1:8-10). His descendants are called in the AV. Ethiopians, though the Hebrew is the same: Cush. The district also occupied by the above people (Isa. 11:11), is mostly called in AV, Ethiopia. It will be seen by the genealogy that the descendants of Cush were numerous:
All these cannot be confined to Africa. Some were probably located in Arabia, and Nimrod is clearly associated with the East; so that though as a district Cush may usually refer to Africa, the Cushites must have had a much wider range. It seems clear too from Genesis 2:13 that even geographically the name Cush, or Ethiopia, was also applied to a region in Asia.
2. A Benjamite enemy of David (Psalm 7 title). Some consider that Shimei is referred to (2 Sam. 16:5, as intimated in the margin). Others think it is Saul.
“Ethiopia” From Concise Bible Dictionary:
This is the Greek and Roman name for Cush, a kingdom in Africa to the south of Egypt. The boundary between the two kingdoms is not well defined, indeed, it may have varied at different times. The first cataract, 24° N, is generally taken as its northern boundary: its extent southward is altogether unknown (Gen. 2:13; Esther 1:1; Ezek. 29:10). At times Ethiopia conquered Egypt: two of the kings mentioned in scripture were Ethiopians (2 Chron. 14:9; Isa. 37:9). In some of the prophecies they are mentioned as separate kingdoms (Nah. 3:9). See EGYPT, LAND OF.
