(1) An African kingdom located along the Nile River to the south of Egypt, in the region that is now part of the country of Sudan. The Hebrew terms “Cush” and “Cushite” occur over fifty times in the OT. Since the Greeks used the term “Ethiopia” in a generic sense to refer to everything south of Egypt, including Cush, and some historians occasionally refer to the Cushite kingdom as Nubia, English Bible versions occasionally translate the Hebrew term “Cush” as “Ethiopia” or “Nubia.” Likewise, the NT character referred to as the “Ethiopian eunuch” (Acts 8:27) was not from modern Ethiopia but rather from this same kingdom on the Nile, south of Egypt, called “Cush” throughout the OT.
Cush is an identifiable political entity as early as 2500 BC, but for most of its early history it was under Egyptian domination. In the late eighth century BC, however, Cush began to grow and expand its influence, and by 710 BC Cush had conquered Egypt and set up its own dynasty of Cushite pharaohs. The Cushites ruled Egypt until 663 BC, when the Assyrians finally drove them out of Egypt.
Cush and the Cushites play several important roles in the Bible. Moses married a Cushite woman (Num. 12:1). Cushites made up a significant part of Egyptian society, so Moses would have had numerous points of contact with Cushites. In the time of the monarchies a Cushite general, Zerah, led an unsuccessful expedition against Israel (2 Chron. 14:9–15). Later in history Cush became a critical part of the historical background of 2 Kings and Isaiah. During this era, the Cushites developed into the superpower to the south of Israel and Judah that contended with Assyria, the superpower to the north. Thus, for much of the time of Isaiah, the Cushites appeared to be allied with Judah against the Assyrians. When the Assyrians attacked Jerusalem in 701 BC, the Cushite king Tirhakah sent an army from Egypt northward to Judah, to attempt to relieve Jerusalem.
The Cushites were particularly famous throughout the ancient Near East as soldiers and mercenaries. Two individual Cushites in the Bible appear in this role: the messenger in David’s army (2 Sam. 18:21) and probably Ebed-Melek (Jer. 38–39).
The OT prophets pronounce judgment on all the surrounding nations for their complicity in the attack on Israel and Judah by the Assyrians and Babylonians. Cush is included among the nations falling under this judgment. However, when the prophets look beyond the destruction to the time of messianic restoration, they paint a picture of people from all nations joining together to worship the true God. The prophets use the Cushites as one of their paradigm groups for this restoration. That is, in the prophetic passages of future restoration, Cush often represents the future Gentile inclusion (Isa. 11:11; 45:14; Zeph. 3:9–10). Ebed-Melek, the Cushite who rescued Jeremiah during the Babylonian siege of Jerusalem, appears to play a similar role in the narrative of Jer. 38–39. That is, while the entire city of Jerusalem turns against God’s word and his true prophet Jeremiah, it is the Cushite Ebed-Melek (representing the Gentiles) who believes and trusts in God, thus finding deliverance instead of death (Jer. 39:15–18). In the NT, the Ethiopian eunuch (an official from Cush) is similar in several respects to Ebed-Melek in the book of Jeremiah (Acts 8:26–40). At a time when Jerusalem has rejected the message of God and is actively persecuting God’s messengers (Acts 7:1–8:3), it is an Ethiopian (Cushite) official who believes. Thus, in a fashion similar to Ebed-Melek, this Ethiopian (Cushite) probably symbolizes the inclusion of Gentiles into the people of God.
(2) The superscription of Ps. 7 (7:1 MT) states that David sang this psalm to God concerning a Benjamite named “Cush,” apparently one of David’s enemies. It is not known why this individual and the Cushi of Zeph. 1:1, who apparently were Hebrews, were so named. Perhaps they were Cushites, or perhaps one of their parents was a Cushite. On the other hand, perhaps they were given the name in honor of a certain Cushite. (See also Cushi.)
(3) Another reference to someone named “Cush” is in the puzzling passage Gen. 10:6–8 (restated in 1 Chron. 1:8–10). Genesis 10, however, is a notoriously difficult chapter to interpret. It consists largely of a genealogy, but the names used in the genealogy include those of individuals, peoples, countries, tribes, and cities. Some scholars think that the chapter is more about geopolitical alliances and geographical locations than about physical descent of individuals. In Gen. 10:6 Cush is said to be the father of Nimrod. Little is known for certain about Nimrod, but in Gen. 10:10–12 he is closely associated with various cities and kingdoms in Mesopotamia. Thus, some scholars associate this reference to Cush with some entity in Mesopotamia, perhaps a people known as the Cassites. On the other hand, in Gen. 10:6 Cush is closely associated with Egypt (Mizraim), as was the historical kingdom of Cush, which was just to the south of Egypt. Likewise, the “sons” of Cush listed in Gen. 10:7 are cities, regions, or individuals normally associated with Arabia, the Red Sea region, or the area south of Egypt (Cush). Consequently, there is no consensus among scholars as to how the term “Cush” is used in Gen. 10:6–8.
