Joseph Smith, Jr. (at Harmony, Susquehanna, PA) claimed to receive a message from God directed to Oliver Cowdery (LDS D&C Sec. 6). Cowdery was told in the text that God had given him a "gift" by which he (Oliver) would "assist in bringing to light" "those parts of the scriptures which have been hidden..." He was further told that his "gift" would allow him "to translate, even as my servant Joseph" and that he would receive no greater witness of the supposedly ancient record. It is possible that the "gift" mentioned in the "revelation" pertained in some way to Oliver's using a diving rod to locate and/or "translate" ancient scriptural records.
