Revelation given through Joseph Smith the Prophet, at Nauvoo, Illinois, recorded 12 July 1843, relating to the new and everlasting covenant, including the eternity of the marriage covenant, and also the plurality of wives (see History of the Church, 5:501–7). Although the revelation was recorded in 1843, it is evident from the historical records that the doctrines and principles involved in this revelation had been known by the Prophet since 1831.
