18 There were three sons of Zeruiah there, Joab and Abishai and Asahel: and Asahel was as quick-footed as a roe of the fields. 19 Asahel went running after Abner, not turning to the right or to the left. 20 Then Abner, looking back, said, Is it you, Asahel? And he said, It is I. 21 And Abner said, Then go to the right or to the left and put your hands on one of the fighting-men and take his arms. But Asahel would not be turned away from going after Abner. 22 Then again Abner said to Asahel, Go to one side, do not keep on coming after me: why will you make me put an end to you? for then I will be shamed before your brother Joab. 23 But still he did not go to one side: so Abner gave him a back blow in the stomach with his spear, so that the spear came out at his back; and he went down on the earth, wounded to death: and all those who came to the place where Asahel went down dead, came to a stop. 24 But Joab and Abishai went after Abner: and the sun went down when they came to the hill of Ammah, which is to the east of the road through the waste land of Geba.

(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.
