[Polygamy] Already married, 19 year-old Zina remained conflicted with Smith's polygamy proposal "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." They were secretly married within days. Smith tells 19 year-old married woman that she must marry him or an angel with a sword will slay him . SOURCE: In Sacred Loneliness, page 80-,81
