2 Samuel 20:9-11

American Standard Version

⁹ And Joab said to Amasa, Is it well with thee, my brother? And Joab took Amasa by the beard with his right hand to kiss him. ¹⁰ But Amasa took no heed to the sword that was in Joab’s hand: so he smote him therewith in the body, and shed out his bowels to the ground, and struck him not again; and he died.

And Joab and Abishai his brother pursued after Sheba the son of Bichri. ¹¹ And there stood by him one of Joab’s young men, and said, He that favoreth Joab, and he that is for David, let him follow Joab.
