2 Samuel 20:9; 2 Samuel 20:10

9 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.

10 But Amasa was not on guard against the sword which was in Joab's hand so he struck him in the belly with it and poured out his inward parts on the ground, and did not strike him again, and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
