And the king said, Is not the hand of Joab with you in all this? And the woman answered and said, As your soul lives, my lord the king, none can turn to the right hand or to the left from anything that my lord the king has spoken: for your servant Joab, he bade me, and he put all these words in the mouth of your handmaid:

And he cast stones at David, and at all the servants of king David: and all the people and all the mighty men were on his right hand and on his left.

And Joab said to Amasa, Are you in health, my brother? And Joab took Amasa by the beard with the right hand to kiss him.
