Jewish and Christian interpretations A question arising early in the story is why God rejected Cain's sacrifice. The text states, "In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. And Abel also brought an offering: fat portions from some of the firstborn of his flock. The Lord looked with favor on Abel and his offering, but on Cain and his offering he did not look with favor." Noteworthy is the difference in the type of sacrifice: fruits of the soil are renewable and bloodless, while fat portions are set apart for the Lord and taken from the firstborn, pointing to an act of faith, since it is not guaranteed there will be more. The
Midrash suggests that although Abel brought the best meat from his flock, Cain did not set aside the best of his harvest for God. Similar to the internalized spiritual death, God warns Adam and Eve off from eating the forbidden fruit—they do not physically die immediately, but over time, their bodies age and die—the Lord warns Cain that his inappropriate anger is waiting to consume him: "If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door. It desires to have you, but you must rule over it.
Curse and mark According to , Cain treacherously murdered his brother, Abel, and then
lied about the murder to God. As a result, Cain was cursed and marked for life. With the earth left cursed to drink Abel's blood, Cain could no longer farm the land. He becomes a "fugitive and wanderer" and receives a mark from Godcommonly referred to as the
mark of Cainso that no one can enact vengeance on him.
Exegesis of the
Septuagint's narrative, "groaning and shaking upon the earth", has Cain suffering from body tremors. Interpretations extend Cain's curse to his descendants, where they all died in the
Great Deluge as retribution for the loss of Abel's potential offspring.
Islamic interpretation Cain's name in Islamic tradition is Qabil (). His story is mentioned in the
Quran, though without a name, where he and his brother
Abel offer sacrifices; Abel's sacrifice was accepted while Cain's was not. Cain gets angry and threatens to murder his brother, but Abel tries to console him, saying that God only accepts sacrifices from the God-fearing and that he would not try to harm Cain. In the end, Cain kills Abel. God sends a
crow searching in the ground to show Cain how to hide the disgrace of his brother. In his shame, Cain began to curse himself and became full of guilt.
Latter-day Saint interpretation The Book of Moses in the
Pearl of Great Price describes the seed of Cain as "black" (Moses 7:22), without explicitly stating whether this description is symbolic or literal. While some early church leaders interpreted this to imply that all people of African descent were descendants of Cain (for example,
Brigham Young taught that
The Mark of Cain could be seen "on the countenance of every African" and used this interpretation as part of the rationale to bar Black men from priesthood ordination in the 19th and 20th centuries), the modern leadership of
The Church of Jesus Christ of Latter-day Saints has formally disavowed such teachings. An official Church statement on race declares that the Church "disavows the theories advanced in the past that black skin is a sign of divine disfavor or curse" and affirms that "all are alike unto God" (2 Nephi 26:33). == Etymology ==
