2 Samuel 20:4-13 - Joab Assassinates Amasa
4 The king said to Amasa, “Summon the men of Judah to me within three days and be here yourself.” 5 Amasa went to summon Judah, but he took longer than the time allotted him. 6 So David said to Abishai, “Sheba son of Bichri will do more harm to us than Absalom. Take your lord’s soldiers and pursue him, or he will find fortified cities and elude us.”
7 So Joab’s men, the Cherethites, the Pelethites, and all the warriors marched out under Abishai’s command;
11 One of Joab’s young men had stood over Amasa saying, “Whoever favors Joab and whoever is for David, follow Joab!” 12 Now Amasa was writhing in his blood in the middle of the highway, and the man had seen that all the people stopped. So he moved Amasa from the highway to the field and threw a garment over him because he realized that all those who encountered Amasa were stopping. 13 When he was removed from the highway, all the men passed by and followed Joab to pursue Sheba son of Bichri.
