1 Samuel 26:14-16

14David shouted to Saul's army and to Ner's son, Abner, ‘Abner, wake up! Answer me!’ Abner replied, ‘Who is shouting to wake up the king? Who are you?’

15David said to Abner, ‘Are you really the bravest soldier in Israel? You should have kept the king safe. Someone came into your camp to kill your master.

16You have not done your job well. You and your men have not protected your master, who is the Lord's chosen king. As surely as the Lord lives, you all deserve to die. The king's spear and his water pot were beside his head. Look where they are now!’
