Abel (Man living at the time before the Flood)

The first name in Jesus's list of murdered prophets, 'from the blood of Abel' (11:51), echoing Genesis 4:10's blood that cries out. 1 Enoch's own vision of the afterlife has Abel's spirit still literally pleading his case in the world of the dead, generations later.

Abel was Adam and Eve's second son, a shepherd whose offering of the firstborn of his flock God accepted while rejecting the offering of his farmer brother Cain, and Cain's resulting jealousy led to history's first murder. Jesus refers to Abel's blood as the first in a long line of righteous blood shed by Israel, and Hebrews credits Abel's faith, not just his offering, as the reason his sacrifice pleased God, adding that his blood still speaks even though he is dead.
