5 But when Amasa went to summon Judah, he took longer than the time the king had set for him. 6 David said to Abishai, "Now Sheba son of Bikri will do us more harm than Absalom did. Take your master's men and pursue him, or he will find fortified cities and escape from us."[1] 7 So Joab's men and the Kerethites and Pelethites and all the mighty warriors went out under the command of Abishai. They marched out from Jerusalem to pursue Sheba son of Bikri. 8 While they were at the great rock in Gibeon, Amasa came to meet them. Joab was wearing his military tunic, and strapped over it at his waist was a belt with a dagger in its sheath. As he stepped forward, it dropped out of its sheath. 9 Joab said to Amasa, "How are you, my brother?" Then Joab took Amasa by the beard with his right hand to kiss him. 10 Amasa was not on his guard against the dagger in Joab's hand, and Joab plunged it into his belly, and his intestines spilled out on the ground. Without being stabbed again, Amasa died. Then Joab and his brother Abishai pursued Sheba son of Bikri.
5 So Amasa went to assemble the men of Judah: but he tarried longer than the set time which he had appointed him. 6 And David said to Abishai, Now shall Sheba the son of Bichri do us more harm than did Absalom: take thou thy lord's servants, and pursue after him, lest he get him fenced cities, and escape
5 So Amasa went to summon Judah, but he delayed beyond the set time that had been appointed him. 6 And David said to Abishai, "Now Sheba the son of Bichri will do us more harm than Absalom. Take your lord's servants and pursue him, lest he get himself to fortified cities and escape from us."
5 Amasa went to carry out his orders, but he was late reporting back. 6 So David told Abishai, "Sheba son of Bicri is going to hurt us even worse than Absalom did. Take your master's servants and hunt him down before he gets holed up in some fortress city where we can't get to him." 7 So under Abishai's command, all the best men - Joab's men and the Kerethites and Pelethites - left Jerusalem to hunt down Sheba son of Bicri. 8 They were near the boulder at Gibeon when Amasa came their way. Joab was wearing a tunic with a sheathed sword strapped on his waist, but the sword slipped out and fell to the ground. 9 Joab greeted Amasa, "How are you, brother?" and took Amasa's beard in his right hand as if to kiss him. 10 Amasa didn't notice the sword in Joab's other hand. Joab stuck him in the belly and his guts spilled to the ground. A second blow wasn't needed; he was dead. Then Joab and his brother Abishai continued to chase Sheba son of Bicri.
5 So Amasa went to assemble the men of Judah. But he delayed longer than the set time which David had appointed him. 6 And David said to Abishai, "Now Sheba the son of Bichri will do us more harm than Absalom. Take your lord's servants and pursue him, lest he find for himself fortified cities, and escape us." 7 So Joab's men, with the Cherethites, the Pelethites, and all the mighty men, went out after him. And they went out of Jerusalem to pursue Sheba the son of Bichri. 8 When they were at the large stone which is in Gibeon, Amasa came before them. Now Joab was dressed in battle armor; on it was a belt with a sword fastened in its sheath at his hips; and as he was going forward, it fell out. 9 Then Joab said to Amasa, "Are you in health, my brother?" And Joab took Amasa by the beard with his right hand to kiss him. 10 But Amasa did not notice the sword that was in Joab's hand. And he struck him with it in the stomach, and his entrails poured out on the ground; and he did not strike him again. Thus he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
5 So Amasa went out to notify Judah, but it took him longer than the time he had been given. 6 Then David said to Abishai, "Sheba son of Bicri is going to hurt us more than Absalom did. Quick, take my troops and chase after him before he gets into a fortified town where we can't reach him." 7 So Abishai and Joab, together with the king's bodyguard and all the mighty warriors, set out from Jerusalem to go after Sheba. 8 As they arrived at the great stone in Gibeon, Amasa met them. Joab was wearing his military tunic with a dagger strapped to his belt. As he stepped forward to greet Amasa, he slipped the dagger from its sheath. 9 "How are you, my cousin?" Joab said and took him by the beard with his right hand as though to kiss him. 10 Amasa didn't notice the dagger in his left hand, and Joab stabbed him in the stomach with it so that his insides gushed out onto the ground. Joab did not need to strike again, and Amasa soon died. Joab and his brother Abishai left him lying there and continued after Sheba.

Commentary on 2 Samuel 20:4-13
(Read 2 Samuel 20:4-13)
Joab barbarously murdered Amasa. The more plot there is in a sin, the worse it is. Joab contentedly sacrificed the interest both of the king and the kingdom to his personal revenge. But one would wonder with what face a murderer could pursue a traitor; and how, under such a load of guilt, he had courage to enter upon danger: his conscience was seared.
