Now David had said, “Whoever is the first to strike down a Jebusite will become chief commander.”And Joab son of Zeruiah went up first, and he became the chief.

Their sisters were Zeruiah and Abigail. And the three sons of Zeruiah were Abishai, Joab, and Asahel.

Moreover, you know what Joab son of Zeruiah did to me—what he did to Abner son of Ner and Amasa son of Jether, the two commanders of the armies of Israel. He killed them in peacetime to avenge the blood of war. He stained with the blood of war the belt around his waist and the sandals on his feet.

Then Abishai son of Zeruiah said to the king, “Why should this dead dog curse my lord the king? Let me go over and cut off his head!”

So Joab son of Zeruiah, along with the servants of David, marched out and met them by the pool of Gibeon. And the two camps took up positions on opposite sides of the pool.
