2 Samuel 20:9-12

9Joab said to Amasa, “Is it going well with you, my brother?” And with his right hand Joab took hold of Amasa by the beard [as if] to kiss him [in greeting].

10But Amasa [who had replaced Joab as David’s commander] was off guard and not attentive to the sword in Joab’s hand. So Joab struck Amasa in the abdomen with the sword, spilling his intestines to the ground. Without another blow Amasa died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.

11Now one of Joab’s young men stood by him and said, “Whoever favors Joab and is for David, let him follow Joab!”

12But Amasa was wallowing in his blood in the middle of the highway. And when the man saw that all the people who came by stopped [to look], he moved Amasa from the highway into the field and threw a garment over him when he saw that everyone who came by Amasa stopped.
