"His brother, Hyrum, said to me, "Now, Brother Benjamin, you know that Brother Joseph would not sanction this if it was not from the Lord. The Lord revealed this to Brother Joseph long ago, and he put it off until the Angel of the Lord came to him with a drawn sword and told him that he would be slain if he did not go forth and fulfill the law." He told my sister to have no fears, and he there and then sealed my sister, Almira, to the Prophet."
"Soon after this he was at my house again, where he occupied my Sister Almira's room and bed, and also asked me for my youngest sister, Esther M. I told him she was promised in marriage to my wife's brother. He said, "Well, let them marry, for it will all come right.""

"He further said that my sister, Eliza R. Snow, had been sealed to him as his wife for time and eternity. He told me that the Lord would open the way, and I should have women sealed to me as wives. This conversation was prolonged, I think, one hour or more, in which he told me many important things."
"I solemnly declare before God and holy angels, and as I hope to come forth in the morning of the resurrection, that the above statement is true."

http://www.Mormons.org.uk/celest.htm"19 year-old Zina remained conflicted until a day in October, apparently, when Joseph sent [her older brother] Dimick to her with a message: an angel with a drawn sword had stood over Smith and told him that if he did not establish polygamy, he would lose "his position and his life." Zina, faced with the responsibility for his position as prophet, and even perhaps his life, finally acquiesced." (In Sacred Loneliness, page 80-81)
"An Angel of God Stood by him (Joseph Smith) with a drawn Sword and told him he should be slain & Cut off from the Earth and the kingdom of God if he did not obey that Law (of polygamy). George Q Cannon was of the same opinion, that a man must have more then one wife at a time in order to obey that Law."
