1 Samuel 17:47-49

Young's Literal Translation

⁴⁷ and all this assembly do know that not by sword and by spear doth Jehovah save, that the battle [is] Jehovah's, and He hath given you into our hand.'

⁴⁸ And it hath come to pass, that the Philistine hath risen, and goeth, and draweth near to meet David, and David hasteth and runneth to the rank to meet the Philistine,

⁴⁹ and David putteth forth his hand unto the vessel, and taketh thence a stone, and slingeth, and smiteth the Philistine on his forehead, and the stone sinketh into his forehead, and he falleth on his face to the earth.
