'Abdomen' in the Bible

But Asahel refused to turn aside. So Abner struck him in the abdomen with the back end of his spear. The spear came out his back; Asahel collapsed on the spot and died there right before Abner. Everyone who now comes to the place where Asahel fell dead pauses in respect.

When Abner returned to Hebron, Joab took him aside at the gate as if to speak privately with him. Joab then stabbed him in the abdomen and killed him, avenging the shed blood of his brother Asahel.

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.
