Joseph Smith's Revelation Regarding the Choir Leader

During a meeting in Nauvoo, the Prophet Joseph Smith received a revelation while marking in the dust with a cane. He informed the congregation and his wife, Emma Smith, that the leader of the choir had committed adultery and that a woman in the choir was involved. The leader and the woman subsequently fled Nauvoo, confirming the Prophet's inspired discernment.

Fuller account of this event (in the witness’s own words):

I will relate one circumstance which I know to be true. I was in the choir in Nauvoo. The Prophet Joseph Smith came into the meeting, and after the second singing, he returned to the stand, and said to his wife who was in the choir, 'Emma, I don’t want you to sing in that choir any more,' and to the audience, 'I went down and took Dimick’s place awhile, and while I marked in the dust with his cane, I inquired of the Lord if that choir was singing praises to Him acceptably. He showed me that the leader of that choir had committed adultery, and that the woman was in the choir also. I don’t want you to sing in that choir any more, Emma.' The leader and the woman were both present, and they both left the city of Nauvoo that same day, and never returned.
