While working on the translation of the Bible in the early 1830s, the Prophet Joseph Smith became troubled by the fact that Abraham, Jacob, David, and other Old Testament leaders had more than one wife. The Prophet prayed for understanding and learned that at certain times, for specific purposes, following divinely given laws, plural marriage was approved and directed by God. Joseph Smith also learned that with divine approval, some Latter-day Saints would soon be chosen by priesthood authority to marry more than one wife. A number of Latter-day Saints practiced plural marriage in Nauvoo, but a public announcement of this doctrine and practice was not made until the August 1852 general conference in Salt Lake City. At that conference, Elder Orson Pratt, as directed by President Brigham Young, announced that the practice of a man having more than one wife was part of the Lord’s restitution of all things (see Acts 3:19–21).
