1 Samuel (Author Compiled by Isaiah from records of Samuel, David, Nathan, and Gad.)
17:51and David runneth and standeth over the Philistine, and taketh his sword, and draweth it out of its sheath, and putteth him to death, and cutteth off with it his head; and the Philistines see that their hero is dead, and flee.
