A worthless man named Sheba, son of Bichri, a Benjaminite, blows the trumpet and proclaims that they have no portion in David and no inheritance in the son of Jesse. The men of Israel leave David, but the men of Judah stay with their king from the Jordan to Jerusalem. On returning home, David puts the ten concubines Absalom had taken under guard, living as widows until the day of their death.
David orders Amasa to summon Judah within three days, but he delays. So the king sends Abishai to pursue Sheba before he can fortify cities. Joab and the men go out with Abishai. At the great stone in Gibeon they meet Amasa. Joab carries a hidden sword, approaches Amasa, asks whether he is well, takes him by the beard with his right hand to kiss him, and with the sword in his left strikes him in the belly, and he dies. Joab and Abishai pursue Sheba. One of Joab's men calls to the people that whoever favors Joab should follow Joab. Amasa lies in the road, and they move him aside so the people can advance.
Sheba passes through the tribes to Abel of Beth-maacah, and Joab besieges the city, raising a siege mound. A wise woman calls from the wall and asks why he wants to destroy a mother in Israel. Joab answers that he does not intend to destroy, only to have Sheba handed over. The woman promises to throw his head over the wall. She speaks to the people with wisdom, and they cut off Sheba's head and throw it to Joab. Joab blows the trumpet, the men disperse and he returns to Jerusalem. The chapter ends with the list of David's officials, among them Joab, Benaiah, Adoram over the forced labor, and Zadok and Abiathar as priests.
