1 Samuel (Author Compiled by Isaiah from records of Samuel, David, Nathan, and Gad.)
Chapter 26
16This thing is not good that thou hast done. As the LORD liveth, ye are worthy to die, because ye have not kept your master, the LORD'S anointed. And now see where the king's spear is, and the cruse of water that was at his bolster.
