TSK · 2 Samuel 13:26

When Abner was returned to Hebron, Joab took him aside into the midst of the gate to speak with him quietly, and struck him there in the body, so that he died, for the blood of Asahel his brother.

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

A malicious man disguises himself with his lips, but he harbors evil in his heart.
