2 Samuel 20:1-10

There happened to be there a worthless and wicked man named Sheba the son of Bichri, a Benjamite. He blew a trumpet [to call Israel to revolt] and said, “We have no portion in David And no inheritance in the son of Jesse, Every man to his tents, O Israel!” So all the men of Israel deserted David and followed Sheba the son of Bichri; but the men of Judah stayed faithfully with their king, from the Jordan to Jerusalem. Then David came to his house (palace) at Jerusalem, and the king took the ten women, his concubines whom he had left to take care of the house, and placed them under guard and provided for them, but did not go in to them. So they were confined, and lived as widows until the day of their death. Now the king said to Amasa [the commander of his army], “Summon the [fighting] men of Judah to me within three days, and be present here yourself.” So Amasa went to summon [the fighting men of] Judah, but he delayed longer than the time which David had set for him. And David said to Abishai [his nephew], “Now Sheba the son of Bichri will do us more harm than Absalom did. Take your lord’s servants and pursue him, so that he does not find fortified cities for himself and escape from our sight.” So Joab’s men went after him, along with [David’s bodyguards] the Cherethites and Pelethites and all the warriors; they went out from Jerusalem to pursue Sheba the son of Bichri. When they were at the great stone in Gibeon, Amasa came to meet them. Now Joab was wearing his military uniform, and over it he had a belt with a sheathed sword strapped around his hips; and as he went forward, it fell out. Joab said to Amasa, “Is it going well with you, my brother?” And with his right hand Joab took hold of Amasa by the beard [as if] to kiss him [in greeting]. But Amasa [who had replaced Joab as David’s commander] was off guard and not attentive to the sword in Joab’s hand. So Joab struck Amasa in the abdomen with the sword, spilling his intestines to the ground. Without another blow Amasa died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
