Assisted by Elders H. [Heber] C. Kimball and Geo. [George] A. Smith, I spent several days laboring with Elder Orson Pratt, whose mind became so darkened by the influence and statements of his wife, that he came out in rebellion against Joseph, refusing to believe his testimony or obey his counsel. [Sarah Pratt maintained that Joseph Smith had proposed to her while Orson was on a mission in England.] He said he would believe his wife in preference to the Prophet. Joseph told him if he did believe his wife and follow her suggestions, he would go to hell.
We reported to the Prophet that we had labored with Brother Orson [Pratt] diligently in a spirit of meekness, forbearance and long-suffering. He requested us to ordain Brother Amasa Lyman in Brother Orson's stead. After receiving these instructions, we met Brother Orson near my house, and continued to labor with him. He said to us, There is Brother Amasa Lyman in your house, Brother Young; he has been long in the ministry, go in and ordain him in my stead.
