Cain and Abel

In the Genesis narrative Cain (Hebrew Kayin) and Abel (Hebrew Hevel) are the first offspring of Adam and Eve, born in the primeval period immediately following the creation and expulsion episodes. Both bring offerings to the Lord—Cain from the fruit of the ground, Abel from the firstlings of his flock—and God has regard for Abel's offering but not Cain's. Cain becomes very angry, lures Abel into the field, and kills him. God confronts Cain, who denies knowledge of his brother ('Am I my brother's keeper?'), pronounces a curse upon him (the ground will no longer yield easily for him; he will be a fugitive and wanderer), but also declares that whoever kills Cain will suffer sevenfold vengeance and places a mark on Cain so that he will not be slain by others. Afterward Cain departs to the land of Nod east of Eden, builds a city named Enoch after his son, and fathers descendants. Later interpretive traditions reread the episode: the New Testament (e.g., Hebrews) portrays Abel's offering as acceptable because offered in faith and uses Cain as a negative moral exemplar; Islamic summaries portray Cain (Qābīl) as driven by jealousy and guided by the devil; Gnostic (Sethian) texts present variant cosmologies reinterpreting names like Cain and Abel as archonic figures.

The primary sources provide no physical description of Cain or Abel. Instead the narrative distinguishes them by social role and activity: Cain as a tiller of the ground (farmer, settled agriculturalist) and Abel as a keeper of sheep (shepherd, pastoralist). Their Hebrew names also carry semantic weight—Kayin is associated with acquisition/possession and Hevel with transience or vanity—which informs literary and theological readings of their characters. Beyond these occupational markers and names, bodily features or apparel are not attested in the cited materials.

As narrated in Genesis the brothers are ordinary human actors rather than supernatural agents. Their noted capacities are social and behavioral: Cain works the soil and offers produce; Abel tends flocks and offers the firstlings and fat portions. The narrative ascribes to Cain emotions and actions—anger, a fallen countenance, the decision to murder, and subsequent fear and despair—and to God the power to accept or reject offerings, to judge and curse, to announce protective vengeance on Cain's behalf, and to mark Cain. Later traditions characteristically reinterpret their roles (e.g., Hebrews emphasizes Abel as exemplary faith; Islamic summaries attribute malicious prompting to the devil; Gnostic variants recast the names within archonic cosmologies), but the sources do not ascribe inherent supernatural powers to Cain or Abel themselves.
