Abishai was the brother of Joab son of Zeruiah. Abishai was the leader of the Three Heroes. He used his spear against 300 enemies and killed them. He became as famous as the Three.
The Ammonites saw that the Arameans were running away, so they ran away from Abishai and went back to their city. So Joab came back from the battle with the Ammonites and went back to Jerusalem.
He separated the people into three groups and sent them out. Joab led a third of the men. Joab’s brother, Abishai son of Zeruiah, led another third. And Ittai from Gath led the last third. King David said to the people, “I will also go with you.”
Amasa didn’t see the knife that was now in Joab’s other hand. Joab stabbed him in the belly, and Amasa’s intestines spilled out on the ground. There was no need for Joab to stab him again; he was already dead. Then Joab and his brother Abishai resumed the chase after Sheba son of Bicri.
An enemy might be able to defeat one person, but two people can stand back-to-back to defend each other. And three people are even stronger. They are like a rope that has three parts wrapped together—it is very hard to break.
