On 12 January 1845 Brigham Young told the Nauvoo high priests quorum that he needed fifty men from the quorum to go on a mission “as agents of the Church.” Three days later Young met with the chosen men, gave them assignments throughout the United States, and instructed them to “go into the branches and tell the presiding Elder what you want, and see what they can do for the temple. Tell them it is their duty to tithe themselves. Gather up all the means you can. Make depots, and bring up all the means and men you can to stay all summer.” Though providing means for the Nauvoo House was not listed among the earlier assignments for these missionaries, the renewed interest in that project likely meant that the resources the missionaries gathered would be divided between the Nauvoo temple and the Nauvoo House. The Times and Seasons explained that the missionaries would “collect donations and tithings for the Temple in the city of Nauvoo, and for other purposes.” (High Priests Quorum Record, 12 and 15 Jan. 1845; Newel K. Whitney and George Miller, “To Whom It May Concern,” Times and Seasons, 15 Jan. 1845, 6:780–781.)
