Ecclesiastes 3:14
              I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor any thing taken from it: and God doeth it, that men should fear before him. 
           
                
              Ecclesiastes 10:10
              If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
