18 And there were three sons of Zeruiah there, Joab, and Abishai, and Asahel. Now Asahel was swift of foot, as one of the gazelles that are in the field. 19 And Asahel pursued after Abner; and in going he turned not to the right hand nor to the left from behind Abner. 20 Then Abner looked behind him, and said, Art thou Asahel? And he said, I am. 21 And Abner said to him, Turn thee aside, to thy right hand or to thy left, and lay hold of one of the young men, and take for thyself his armour. But Asahel would not turn aside from following him. 22 And Abner said again to Asahel, Turn thee aside from following me: why should I smite thee to the ground? how then should I hold up my face to Joab thy brother? 23 But he refused to turn aside; therefore Abner with the hinder end of the spear smote him in the belly, 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.
