2 Samuel 20:8-12

8When they were at the great stone that is in Gibeon, Amasa came to meet them. Now Joab was wearing a soldier's garment, and over it was a belt with a sword in its sheath fastened on his thigh, and as he went forward it fell out.

9And Joab said to Amasa, "Is it well with you, my brother?" And Joab took Amasa by the beard with his right hand to kiss him.

10But Amasa did not observe the sword that was in Joab's hand. So Joab struck him with it in the stomach and spilled his entrails to the ground without striking a second blow, and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.

11And one of Joab's young men took his stand by Amasa and said, "Whoever favors Joab, and whoever is for David, let him follow Joab."

12And Amasa lay wallowing in his blood in the highway. And anyone who came by, seeing him, stopped. And when the man saw that all the people stopped, he carried Amasa out of the highway into the field and threw a garment over him.
