18 The three sons of Zeruiah were there, Joab, Abishai, and Asahel. Now Asahel was as swift of foot as a wild gazelle. 19 Asahel pursued Abner, turning neither to the right nor to the left as he followed him. 20 Then Abner looked back and said, "Is it you, Asahel?" He answered, "Yes, it is." 21 Abner said to him, "Turn to your right or to your left, and seize one of the young men, and take his spoil." But Asahel would not turn away from following him. 22 Abner said again to Asahel, "Turn away from following me; why should I strike you to the ground? How then could I show my face to your brother Joab?" 23 But he refused to turn away. So Abner struck him in the stomach with the butt of his spear, so that the spear came out at his back. He fell there, and died where he lay. And all those who came to the place where Asahel had fallen and died, stood still.

(Read 2 Samuel 2:18-24)
Death often comes by ways we least suspect. We are often betrayed by the accomplishments we are proud of! Asahel's swiftness, which he presumed so much upon, did him no service, but hastened his end.
