1 Samuel 26:15-16

“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!”
