1 Samuel 26:13-14
13-14Then David went across to the opposite hill and stood far away on the top of the mountain. With this safe distance between them, he shouted across to the army and Abner son of Ner, "Hey, Abner! How long do I have to wait for you to wake up and answer me?"
Abner said, "Who's calling?"
15-16"Aren't you in charge there?" said David. "Why aren't you minding the store? Why weren't you standing guard over your master the king, when a soldier came to kill the king your master? Bad form! As God lives, your life should be forfeit, you and the entire bodyguard. Look what I have—the king's spear and water jug that were right beside his head!"
