2 Samuel 20:8-10

New Catholic Bible

⁸ When they arrived at the large stone in Gibeon, Amasa came forth from the opposite direction to meet them. Joab was wearing his tunic, and over it was a belt with a sword in its sheath fastened at his waist. As he moved forward, the sword fell loose from his sheath. ⁹ Then Joab said to Amasa: “I trust that you are well, my brother.” Having said that, Joab grasped Amasa’s beard with his right hand as if to kiss him.

¹⁰ Amasa was not on his guard and failed to notice the sword in Joab’s left hand. Joab struck him with it in the belly so that his entrails poured forth to the ground. He did not find it necessary to strike a second blow, since Amasa had died instantaneously. Then Joab set forth with his brother Abishai in pursuit of Sheba, son of Bichri.
