2 Samuel 20:10 NCV

[10] Amasa was not watching the sword in Joab's hand. So Joab pushed the sword into Amasa's stomach, causing Amasa's insides to spill onto the ground. Joab did not have to stab Amasa again; he was already dead. Then Joab and his brother Abishai continued to chase Sheba son of Bicri.
