JS receives a revelation to be sealed to SAW.
"Revelation, 27 July 1842," p. [1-2], The Joseph Smith Papers website, accessed September 7, 2021
Verily, thus saith the Lord unto my servant N. K. Whitney, the thing that my servant Joseph Smith has made known unto you and your family and which you have agreed upon, is right in mine eyes, and shall be crowned upon your heads with honor and immortality and eternal life to all your house both old and young. Because of the lineage of my Priesthood, saith the Lord, it shall be upon you and upon your children after you from generation to generation, by virture of the holy promise which I now make unto you, saith the Lord. These are the words which you shall pronounce upon my servant Joseph and your daughter S. A. Whitney: They shall take each other by the hand, and you shall say, You both mutually agree (calling them by name) to be each other’s companion so long as you both shall live, preserving yourselves for each other and from all others, and also throughout eternity, reserving only those rights which have been given to my servant Joseph by revelation and commandment and by legal authority in times past. If you both agree to covenant and to <do> this, I then give you, S. A. Whitney, my daughter, to Joseph Smith, to be his wife, to observe all the rights between you both that belong to that condition. I do it in my own name and in the name of my wife, your mother, and in the name of my holy progenitors by the right of birth, which is of Priesthood vested in me by revelation, and commandment, and promise of the living God, obtained by the Holy Mechisedek, Jethro, and others of the holy fathers, commanding, in the name of the Lord, all those powers to concentrate in you, and through you to your posterity forever. All these things I do in the name of the Lord Jesus Christ, that through this order He may be glorified, and that through the power of annointing, David may reign King over Israel, which shall hereafter be revealed. Let immortality and eternal life henceforth be sealed upon your heads forever and ever.
