They were at the great stone in Gibeon when Amasa joined them. Joab was wearing his uniform and over it was a belt around his waist with a sword in its sheath. As he approached, [the sword] fell out.
Joab asked Amasa, "Are you well, my brother?" Then with his right hand Joab grabbed Amasa by the beard to kiss him.
Amasa was not on guard against the sword in Joab's hand, and Joab stabbed him in the stomach with it and spilled his intestines out on the ground. Joab did not stab him again for Amasa was dead. Joab and his brother Abishai pursued Sheba son of Bichri.
One of Joab's young men had stood over Amasa saying, "Whoever favors Joab and whoever is for David, follow Joab!"
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.
When he was removed from the highway, all the men passed by and followed Joab to pursue Sheba son of Bichri.
Sheba passed through all the tribes of Israel to Abel of Beth-maacah. All the Berites came together and followed him.

Joab's troops came and besieged Sheba in Abel of Beth-maacah. They built an assault ramp against the outer wall of the city. While all the troops with Joab were battering the wall to make it collapse,
a wise woman called out from the city, "Listen! Listen! Please tell Joab to come here and let me speak with him."
When he had come near her, the woman asked, "Are you Joab?" "I am," he replied. "Listen to the words of your servant," she said to him. He answered, "I'm listening."
She said, "In the past they used to say, 'Seek counsel in Abel,' and that's how they settled [disputes].
I am a peaceful person, one of the faithful in Israel, but you're trying to destroy a city that is like a mother in Israel. Why would you devour the Lord's inheritance?"
Joab protested: "Never! I do not want to destroy!
That is not [my] intention. There is a man named Sheba son of Bichri, from the hill country of Ephraim, who has rebelled against King David. Deliver this one man, and I will withdraw from the city." The woman replied to Joab, "All right. His head will be thrown over the wall to you."
The woman went to all the people with her wise counsel, and they cut off the head of Sheba son of Bichri and threw it to Joab. So he blew the ram's horn, and they dispersed from the city, each to his own tent. Joab returned to the king in Jerusalem.
