The conflict between Cain and Abel and the latter’s death at the hand of his brother Cain, is relatively straightforward. Cain and Abel are probably twins, of which Cain is the first born. After they grow to be young men, Cain kills his brother when his despondency((Following God’s dismissal of Cain’s offering.)) leads to homicidal rage.
There is much to unpack here. First, we’ll see that the setting is a natural follow on to the Garden of Eden and, to some scholars, is thought to have once been part of that narrative. Because I’m sympathetic to this point of view, this translation will terminate at verse 4:16 in which Cain settles in the land of Nod – a natural conclusion to the Garden of Eden story taken through the primeval couple’s immediate life after expulsion.
Second, the theological depth of the story is uncommonly profound, dealing as it does with the value God places on motherhood, the issue of fratricide (one that runs through much of the Hebrew Bible (a.k.a. Old Testament)), and finally how mankind is to deal with the passions that can lead to sin, be they rage, lust, hate, envy, etc.
