Nancy Marinda Hyde, wife of Orson Hyde, is given a priesthood blessing (probably by Joseph Smith Sr.) which states: "The time shall come when thou shalt be left by thy husband, for he must go to foreign lands and preach the gospel, he will be great in the hands of the Lord having a great work to do among the nations of the earth. Thou will have afflictions and sorrow for thy husband-but thou will give him up to his calling and trust in God, thou shall be blest. In the absence of thy companion the angels of heaven shall minister to thee-they will give thee instructions and comfort thy heart." Four years later while her husband Orson is on a mission to Jerusalem, Joseph Smith takes her as a plural wife.
