1 Samuel 26:12-14

12 So David took the spear and the cruse of water that were at Saul's head, and they went, and no one saw [it] nor knew [it] neither awaked, for they [were] all asleep because a deep sleep from the LORD had fallen upon them.

13 Then David went over to the other side and stood out of the way on the top of the mountain, a great space [being] between them;

14 and David cried to the people and to Abner, the son of Ner, saying, Dost thou not answer, Abner? Then Abner answered and said, Who [art] thou [that] dost cry to the king?
