Asahel, a son of
David's sister Zeruiah, was renowned for speed. During fighting at Gibeon between forces supporting David and Ish-bosheth, Asahel pursued Abner relentlessly. Abner repeatedly warned him to turn aside, but Asahel refused, and Abner killed him with the butt of his spear. Asahel's death later became Joab's stated motive for murdering Abner. Chronicles includes Asahel among David's mighty men and records his family line.
