18 Joab, Abishai, and Asahel-the three sons of Zeruiah-were among David's forces that day. Asahel could run like a gazelle, 19 and he began chasing Abner. He pursued him relentlessly, not stopping for anything. 20 When Abner looked back and saw him coming, he called out, "Is that you, Asahel?" "Yes, it is," he replied. 21 "Go fight someone else!" Abner warned. "Take on one of the younger men, and strip him of his weapons." But Asahel kept right on chasing Abner. 22 Again Abner shouted to him, "Get away from here! I don't want to kill you. How could I ever face your brother Joab again?" 23 But Asahel refused to turn back, so Abner thrust the butt end of his spear through Asahel's stomach, and the spear came out through his back. He stumbled to the ground and died there. And everyone who came by that spot stopped and stood still when they saw Asahel lying there.

(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.
