“The Book of Mormon, therefore, is the only record (professing to be Divine) which condemns plurality of wives as being a practice exceedingly abominable before God. But even that sacred book makes an exception in substance as follows—“Except I the Lord command my people.” The same Book of Mormon and the same article that commanded the Nephites that they should not marry more than one wife, made an exception.”Orson Pratt, July 24, 1859 · Polygamy · JD 6:349-364
