20:4 Then the king said to Amasa, “Call the men of Judah together for me in three days, and you be present here with them too.” 20:5 So Amasa went out to call Judah together. But in doing so he took longer than the time that the king had allotted him.
20:6 Then David said to Abishai, “Now Sheba son of Bicri will cause greater disaster for us than Absalom did! Take your lord’s servants and pursue him. Otherwise he will secure fortified cities for himself and get away from us.” 20:7 So Joab’s men, accompanied by the Kerethites, the Pelethites, and all the warriors, left Jerusalem to pursue Sheba son of Bicri.
20:8 When they were near the big rock that is in Gibeon, Amasa came to them. Now Joab was dressed in military attire and had a dagger in its sheath belted to his waist. When he advanced, it fell out.
20:9 Joab said to Amasa, “How are you, my brother?” With his right hand Joab took hold of Amasa’s beard as if to greet him with a kiss. 20:10 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.
