The network of rivers flowing out of the Garden of Eden draws both a geographical and conceptual map of the ancient world. Each waterway is defined by its unique flow, location, and deeper symbolic meaning. The second river is characterized by immense power and speed. Its title reflects water that bursts forward with intense force, creating a loud, rushing roar as it washes over the earth [רש״י, ביאור יש״ר]. It aggressively breaks out and splits into numerous streams to water the surrounding land [רד״ק]. Because its name essentially means a bursting spring, various rivers and water sources throughout history were given this same title, including a famous spring near Jerusalem [שד״ל, רד״ק].
The exact geographical identity of this mighty river is a matter of debate. The primary approach among commentators is to identify it as the Nile, bearing its original name as it passes through a southern territory before reaching Egypt [שד״ל, רד״ק]. This southern land is often thought to be modern-day Ethiopia or a distant mountainous region [ביאור שטיינזלץ]. However, others reject identifying the river with smaller local springs that cannot surround an entire country, or with distant eastern rivers. Instead, they suggest it is the Araxes river, which rushes rapidly into the Caspian Sea, placing the surrounding land nearby in ancient Scythia [ביאור יש״ר]. While this specific nation did not actually exist at the dawn of creation, the Torah deliberately uses a geographic name that would be easily recognized by future generations [דברי דוד]. Unlike a straight-flowing stream, this river winds in a circle, completely encompassing and outlining the borders of the land [רד״ק].
Beyond physical geography, this winding river carries profound moral symbolism. One perspective connects the river's identity—which evokes the image of crawling low to the ground—with a land historically associated with servants, representing a state of lowliness and submission. The river wrapping around this territory carries a comforting message: even simple people in lowly positions who perform their daily work faithfully will earn their rightful reward and a portion in the Garden of Eden [העמק דבר]. A different symbolic approach views the river and its land as a representation of physical urges and material desires. While other rivers might symbolize the aggressive pursuit of power and the breaking of borders through war, this specific river circles its land. This reflects how a person consumed by physical desires constantly turns in circles, trapped within their own limited space and unable to break free from their personal boundaries [מלבי״ם].
