Eden’s rivers. Genesis 2:10 14 describes the garden in Eden as the source of an unnamed river that subsequently divided into four “headwaters”: the Pishon, the Gihon, the Tigris, and the Euphrates. This description defies any attempt to locate the purported site of Eden in terms of historical geography. The Tigris and the Euphrates do not diverge from a common source, but instead converge before emptying into the Persian Gulf. Moreover, the Gihon, if it is to be identified with the sacred spring of the same name in Jerusalem (1 Kings 1:45), is several hundred miles away from the Tigris and the Euphrates. The Pishon is otherwise unknown. If, as various commentators since antiquity have suggested, the Gihon and the Pishon are to be identified with other great rivers in the same class of importance as the Tigris and the Euphrates (the Nile, the Ganges, etc.), then this would further confound any attempt to understand Gen. 2:10–14 in terms of historical geography.
The Nile River. The Nile (Heb. ye’or) is fed by two major tributaries: the White Nile, which begins at Lake Victoria, and the Blue Nile, which begins in Ethiopia. At over four thousand miles, the Nile is the longest river in the world. The ancient civilization of Egypt depended entirely on the flow of the Nile and upon its annual flood (the “gift of the Nile”) for irrigation of crops. Even today, arable land along the Nile is confined in some places to an area no more than a few miles from its banks.
Two of the plagues sent by God upon the Egyptians took place at the Nile, an appropriate setting for a confrontation between the God of Israel and the Egyptian pharaoh, himself a living representation of the Egyptian pantheon. God told Moses to confront Pharaoh at the Nile (Exod. 7:15), and the first plague with which God afflicted the Egyptians consisted of turning the Nile into blood, causing its fish to die and rendering its water unsuitable for drinking. The Egyptians were forced to dig wells along its banks (7:20–21). The second plague involved the multiplication of frogs in the Nile, to the point of great inconvenience (8:3).
Isaiah continues the theme of God punishing the Egyptians by attacking the Nile: “The waters of the river will dry up, and the riverbed will be parched and dry. The canals will stink; the streams of Egypt will dwindle and dry up. The reeds and rushes will wither, also the plants along the Nile” (Isa. 19:5–7).
The Euphrates River. The Euphrates is the westernmost of the two great rivers of Mesopotamia (along with the Tigris [see below]), the land “between the rivers.” As mentioned above, the Euphrates was one of the four rivers flowing from the garden of Eden, according to Gen. 2:14. Along the Euphrates were located the ancient cities of Carchemish, Emar (Tell Meskeneh), Mari, Babylon, and Ur. The Euphrates runs over seventeen hundred miles from northwest to southeast, beginning in the mountains of eastern Turkey before joining with the Tigris and entering the Persian Gulf.
In the Bible, the Euphrates represents the northern boundary of the territory granted to Abraham (Gen. 15:18; see also Exod. 23:31). David extended his territory as far as the Euphrates when he fought the Aramean king Hadadezer (2 Sam. 8:3), and so the dimensions of Israel at its apex under Solomon are described as controlling all the kingdoms “from the Euphrates River to the land of the Philistines, as far as the border of Egypt [i.e., the southern limit of his realm]” (1 Kings 4:21).
The Tigris River. Along with the Euphrates, the Tigris (Heb. khiddeqel) was one of the two rivers of ancient Mesopotamia. The Tigris lies east of the Euphrates and runs over a course of approximately 1,150 miles from northwest to southeast, finally joining with the Euphrates and emptying into the Persian Gulf. In antiquity, the cities of Calah, Nineveh, and Asshur lay along the Tigris. The Tigris is mentioned twice in the Bible: first, as one of the four headwaters emanating from the garden of Eden (Gen. 2:14) and, second, as the location of Daniel’s visionary experience (Dan. 10:4).
The Jordan River. The Jordan (Heb. yarden) runs southward from the Hula Valley into the Sea of Galilee (also known as the Sea of Tiberias; modern Lake Kinneret) and from there through a river valley (the “plain of the Jordan” [see Gen. 13:10]) to the Dead Sea.
In the OT, several memorable stories are set near the Jordan. In addition to Joshua’s dramatic crossing of the Jordan (Josh. 3:1–17), the “fords of the Jordan” were strategic locations, and it was there that the Gileadites slaughtered forty-two thousand Ephraimites as they attempted to return to their territory on the western side of the Jordan (Judg. 12:5). Elisha instructed Naaman, the leprous Aramean general, to bathe seven times in the Jordan for the healing of his condition (2 Kings 5:10). When Elisha’s companions wished to build shelters for themselves, they went to the Jordan, where they knew they would find abundant vegetation and poles (2 Kings 6:2; cf. Zech. 11:3). When one of them dropped an iron ax head into the water, Elisha caused it to float to the surface (2 Kings 6:6–7).
In the NT, the Jordan was the site of much of John the Baptist’s ministry (Matt. 3:5–6; Mark 1:5; Luke 3:3). John 1:28 specifies that John was on the eastern bank (also John 3:26; 10:40). It was in the waters of the Jordan that he baptized those who came to him, including Jesus (Matt. 3:13; Mark 1:9; Luke 3:21).
The wadi of Egypt. In a number of texts the “wadi of Egypt” (or “brook of Egypt”) represents the far southern limit of Israelite territory. Some ancient interpreters understood this as referring to the Pelusian branch of the Nile River delta, while most modern scholars favor the Besor River, farther east, in present-day Israel. Several biblical passages refer to the Shihor River as marking a boundary between Egypt and Israelite territory (Josh. 13:3; 19:26; 1 Chron. 13:5; Isa. 23:3; Jer. 2:18).
The Orontes River. Although it is not mentioned in the Bible, the Orontes marked an important international boundary in the biblical world. The Orontes begins in the Bekaa Valley in present-day Lebanon, then flows northward between the Lebanon and the Anti-Lebanon mountain ranges before turning sharply westward to empty into the Mediterranean Sea. Along the Orontes lay the kingdom of Hamath (see, e.g., 2 Sam. 8:9; 2 Chron. 8:3; Jer. 39:5).
