Asahel

Asahel (Hebrew: עשהאל, Greek: ‘Ασεάλ) (also known as Asael, Asaell, and Assael) is the youngest son of Zeruiah, daughter of Jesse. The name means "Made by God." Asahel was the nephew of King David, as well as the younger brother of both Abishai, David's General, and of Joab. Asahel is mentioned in II Samuel Chapters 2 and 3.

Additionally, the name Asahel (under a variant spelling) appears in Aramaic as was the 10th Watcher of the 20 leaders of the 200 fallen angels that are mentioned in an ancient work called the Book of Enoch.

Meaning
Theophorous "nominal" name appearing in the Bible, made up of two parts: the verb עשה, Hebrew "to do, make" 3rd m.sg. perfect, and the theophorous element (deity name), אל, the Hebrew God El, or Elohim. This would make the name a name of "thanksgiving," thanking God for what he has "made, done."

History
Asael is the youngest son of Zeruiah, David's sister. His old Brothers Joab and Abishai. He was known for his swiftness of foot: "Asahel was swift of foot, like a gazelle in the open field." (cf. IISam. 2:18). He was put to death by Abner, whom he pursued from the battlefield when fighting against Ish-bosheth at Gibeon, in the army of his brother Joab, (cf. IISam. 2:18-19). He is considered among David's thirty valiant men (cf. IISam. 23:24; ICh. 11:26).

After a battle at Gibeon between Abner, commanding the Army of Ish-bosheth son of Saul and Joab, commanding the Army of David, Asahel pursued Abner while he attempted to escape. Young Asahel, who was "swift of foot, like a gazelle in the open field", soon caught up to the veteran General Abner. Abner begged Asahel to stop pursuing him, but when Asahel refused to desist, Abner the blunt end of a spear through Asahel's stomach, and Asahel died on the spot (cf. IISam. 2: 23).

Although Joab won the battle, Abner escaped with his life; Asahel was buried in his father's tomb at Bethlehem. In retaliation, Joab murdered Abner with help from his brother Abishai, against the wishes of David.
