The Genesis Narrative
According to Genesis 4, Abel was the second son born to Adam and Eve. The brothers followed different livelihoods: Abel was a keeper of sheep, while Cain was a tiller of the ground. When each brought an offering to the Lord, Abel presented the firstlings of his flock and their fat portions.
The narrative records that "the Lord had respect unto Abel and to his offering" but had no respect for Cain's offering, which provoked Cain's anger. Cain rose up against his brother and slew him in the field. When God asked Cain where Abel was, Cain denied responsibility with the question "Am I my brother's keeper?" God then declared that the voice of Abel's blood cried out to him from the ground (Genesis 4:10). The account presents Abel's death as the first death and the first murder in the biblical narrative.
