2 Samuel 20:8-13

8As they arrived at the great stone in Gibeon, Amasa met them. Joab was wearing his military tunic with a dagger strapped to his belt. As he stepped forward to greet Amasa, he slipped the dagger from its sheath.

9“How are you, my cousin?” Joab said and took him by the beard with his right hand as though to kiss him.

10Amasa didn’t notice the dagger in his left hand, and Joab stabbed him in the stomach with it so that his insides gushed out onto the ground. Joab did not need to strike again, and Amasa soon died. Joab and his brother Abishai left him lying there and continued after Sheba.

11One of Joab’s young men shouted to Amasa’s troops, “If you are for Joab and David, come and follow Joab.”

12But Amasa lay in his blood in the middle of the road, and Joab’s man saw that everyone was stopping to stare at him. So he pulled him off the road into a field and threw a cloak over him.

13With Amasa’s body out of the way, everyone went on with Joab to capture Sheba son of Bicri.
