“To put this matter more correctly before you, I here declare that the principle of plural marriage was not first revealed on the 12th day of July, 1843. It was written for the first time on that date, but it had been revealed to the Prophet many years before that, perhaps as early as 1832.”Joseph F. Smith, July 7, 1878 · Plural Marriage—For the Righteous Only—Obedience Imperative—Blessings Resulting · JD 20:24-31
