Following the conclusion of his judgment, Cain leaves the scene of his trial and enters a new reality of exile and wandering. The act of leaving the Creator's presence carries profound implications. Some view this departure geographically, suggesting he left a defined physical location near Eden where the Divine presence rested and prophecy was accessible [שד״ל, רד״ק, רב סעדיה גאון]. Others understand it as a spiritual detachment. In this view, he either stepped outside of God's direct, personal protection to become subject to random chance [מלבי״ם], or he intentionally severed his relationship with God to build an independent life devoid of Divine influence [רמב״ן, רש ר הירש].
The physical manner of his exit also reflects his inner state, though perspectives on this vary. He may have departed in shame and submission, turning his back in an attempt to slip away or hide from God [רש״י, מזרחי, גור אריה]. Alternatively, it was a hasty escape from justice, showing a complete lack of genuine remorse [צרור המור]. A contrasting tradition offers a surprisingly different picture: Cain left in high spirits because he had secured a compromise on his sentence. According to this view, he later encountered the first man, who, upon hearing the story, was left astounded by the immense power of repentance [הכתב והקבלה, צאינה וראינה, רא״ש].
A paradox emerges as Cain is said to settle in a land defined by wandering. The primary approach among commentators resolves this by explaining that his partial confession and repentance successfully mitigated the original decree. Rather than roaming the entire globe, his punishment was halved. He was confined to wandering endlessly within the borders of one specific land without ever finding rest, or perhaps his family established a permanent home there while he continued to pace relentlessly [הטור הארוך, מלבי״ם, רד״ק, חזקוני]. Consequently, the name of this region was not its original title, but rather a description applied later because of his endless roaming [אבן עזרא, רמב״ן], or it simply served to describe his constant physical restlessness [נתינה לגר, תורה תמימה]. The reality of this existence was harsh; the earth itself would tremble beneath his feet, and people kept their distance because of his crime [רש״י, מזרחי, שטיינזלץ]. A unique perspective identifies this territory as the Land of Israel, given this specific name in anticipation of the future wanderings the Israelites would experience there [הכתב והקבלה, אדרת אליהו].
The destination of this exile is located to the east of Eden [אבן עזרא, קאסוטו]. This specific direction is highly intentional. The east is traditionally understood as a designated refuge for exiles and murderers. Just as the first man was banished to the east of Eden, the future cities of refuge for accidental killers would also be established in the eastern lands across the Jordan River [רש״י, גור אריה, כלי יקר]. On a deeper conceptual level, sending a murderer to the east carries a message of ultimate repair. A killer takes a life and extinguishes another person's sun. Therefore, he is exiled to the east—the place of the sunrise and the dawn of a new day. This journey embodies the essence of repentance: moving toward the exact opposite extreme of the sin, repairing darkness and death by seeking the source of light and new beginnings [כלי יקר].
