18 And the three sons of Zeruiah were there, Joab, and Abishai, and Asahel: and Asahel was as light of foot as a wild roe. 19 And Asahel pursued after Abner; and in going he turned not to the right hand nor to the left from following Abner. 20 Then Abner looked behind him, and said, Is it thou, Asahel? And he answered, It is I. 21 And Abner said to him, Turn thee aside to thy right hand or to thy left, and lay thee hold on one of the young men, and take thee his armor. But Asahel would not turn aside from following him. 22 And Abner said again to Asahel, Turn thee aside from following me: wherefore should I smite thee to the ground? how then should I hold up my face to Joab thy brother? 23 Howbeit he refused to turn aside: wherefore Abner with the hinder end of the spear smote him in the body, so that the spear came out behind him; and he fell down there, and died in the same place: and it came to pass, that as many as came to the place where Asahel fell down 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.
