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.

Amasa did not protect himself from the knife in Joab's other hand, and Joab stabbed him in the abdomen, causing Amasa's intestines to spill out on the ground. There was no need to stab him again; the first blow was fatal. Then Joab and his brother Abishai pursued Sheba son of Bicri.

But Abishai, the son of Zeruiah, came to his help, and, turning on the Philistine, gave him his death-blow. Then David's men took an oath, and said, Never again are you to go out with us to the fight, so that you may not put out the light of Israel.
