Matthew Henry on 2 Samuel 2:18-24
We have here the contest between Abner and Asahel. Asahel, the brother of Joab and cousin-german to David, was one of the principal commanders of David's forces, and was famous for swiftness in running: he was as light of foot as a wild roe (Sa2 2:18); this he got the name of by swift pursuing, not swift flying.
