TSK · 1 Chronicles 21:6

When Abner returned to Hebron, Joab took him aside at the gate as if to speak privately with him. Joab then stabbed him in the abdomen and killed him, avenging the shed blood of his brother Asahel.

Joab said to Amasa,“How are you, my brother?” With his right hand Joab took hold of Amasa’s beard as if to greet him with a kiss.
