Heber J. Grant hears John W. Taylor tell the Quorum of the Twelve about his (Taylor's) father's 1886 revelation.
Heber J. Grant, Journal, September 30, 1890, 443–444, Church History Library
John W. Taylor, Said that when he had read the Manifesto he felt "damn it" He said that he remembered the Revelation that Prest. Woodruff had had from the Lord which was read to us some time ago in which he told us that He would sustain us in carrying out the law of plural marriage. He also remembered finding among his father's papers the words of the Lord to him in which The Lord said that plural marriage was one of His eternal laws and that he had established it, that man had not done so and that he would sustain and uphold his saints in carrying it out. He said that this was given to his father in answer to prayer in which he had asked the Lord if it would not be right under the circumstances to discontinue plural marriage.
