Absalom had made Amasa general in command of the army in place of Joab. (Now Amasa was the son of an Israelite man named Jether, who had married ¹  Abigail the daughter of Nahash and sister of Zeruiah, Joab’s mother.)

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. ¹ 

Amasa did not protect himself from the knife in Joab’s other hand, and Joab ¹  stabbed him in the abdomen, causing Amasa’s ²  intestines to spill out on the ground. There was no need to stab him again; the first blow was fatal. ³  Then Joab and his brother Abishai pursued Sheba son of Bicri.

Amasa was squirming in his own blood in the middle of the path, and this man had noticed that all the soldiers stopped. Having noticed that everyone who came across Amasa ¹  stopped, the man ²  pulled him ³  away from the path and into the field and threw a garment over him.

So some of ¹  the Ephraimite family leaders, Azariah son of Jehochanan, Berechiah son of Meshillemoth, Jechizkiah son of Shallum, and Amasa son of Hadlai confronted ²  those returning from the battle.
