Revelation given to Joseph Smith the Prophet and Oliver Cowdery, at Harmony, Pennsylvania, April 1829 (see History of the Church, 1:32–35). Oliver Cowdery began his labors as scribe in the translation of the Book of Mormon, 7 April 1829. He had already received a divine manifestation of the truth of the Prophet’s testimony respecting the plates on which was engraved the Book of Mormon record. The Prophet inquired of the Lord through the Urim and Thummim and received this response.
