Oliver Cowdery's Rod

"...now this is not all for thou hast another gift which is the gift of working with the sprout [rod]; Behold it hath told you things; Behold there is no other power save God that can cause this thing of Nature [rod] to work in your hands for it is the work of God & therefore whatsoever ye shall ask to tell you by that means that will he grant unto you that ye shall know remember that without faith ye can do nothing." (D&C 8, see Joseph Smith Papers)
