Final answer:
The question concerns the biblical story of Cain and Abel and its connection to John Steinbeck's novel 'East of Eden.' This novel explores themes of sibling rivalry, parental preference, sin, and redemption, mirroring the biblical account's consequences of jealousy and violence.
Step-by-step explanation:
The biblical story of Cain and Abel from the Book of Genesis serves as the foundation for John Steinbeck's novel East of Eden. Within the narrative, we observe the perpetuation of sibling rivalry and parental preference which mirrors the biblical account.
The dynamics between Cyrus Trask and his sons, as well as the relationship between Adam Trask and his sons, draw parallels to the preference God showed for Abel's offering over Cain's.
In Steinbeck's portrayal of tension and favoritism between siblings, the repercussions include jealousy, passion, and a tragic outcome similar to the demise of Abel by Cain's hand.
The novel explores themes of sin, redemption, free will, and the inherent struggle between good and evil, underlining the significance of choices and the consequences therein.
