Abel was a son of Adam and Eve in the Bible. According to the Bible, he was the first person to die, murdered by his brother Cain.
Who is Abel
Abel (Hebrew: Hevel; Arabic: هابيل, Hābīl) is Eve's second son. His name is composed in Hebrew of the same three consonants as aroot speculated by people to have originally meant "breath", because rabbis postulated one of its roots thus, also "waste", but is used in the Hebrew Bible primarily as a metaphor for what is "elusive", especially the "vanity" (another definition by the rabbis of medieval France, Rashi in specific from his translation into Old French) of human beauty and work e.g. Hevel Hayophi (He-vel Ha-yo-fi) vanity is as beauty from the Song of Songs of Solomon. Julius Wellhausen, and many scholars following him, have proposed that the name is independent of the root. Eberhard Schrader had previously put forward the Akkadian (Old Assyrian dialect) ablu ("son") as a more likely etymology.
The blood of Jesus is interpreted as bringing mercy; but that of Abel as demanding vengeance (hence the curse and mark).
Abel is invoked in the litany for the dying in Roman Catholic Church, and his sacrifice is mentioned in the Canon of the Mass along with those of Abraham and Melchizedek. The Coptic Church commemorates him with a feast day on December 28.
According to the Coptic Book of Adam and Eve (at 2:1-15), and the Syriac Cave of Treasures, Abel's body, after many days of mourning, was placed in the Cave of Treasures, before which Adam and Eve, and descendants, offered their prayers. In addition, the Sethite line of theGenerations of Adam swear by Abel's blood to segregate themselves from the unrighteous.
In the extra-biblical Book of Enoch (22:7), the soul of Abel is described as having been appointed as the chief of martyrs, crying for vengeance, for the destruction of the seed of Cain. This view is later repeated in the Testament of Abraham (A:13 / B:11), where Abel has been raised to the position as the judge of the souls.
