Miraculous healing of Mrs. Johnson's rheumatic arm

In 1831, at the home of Newel K. Whitney in Kirtland, Ohio, Joseph Smith healed Mrs. Johnson (identified in one account as Elsa Johnson), who had been afflicted with a rheumatic arm for years and could not raise her hand to her head. Before the healing, Joseph asked whether she believed the Lord could make him an instrument in healing her; she answered that she did. Joseph bowed his head in silent prayer, took her by the hand, and commanded her in the name of Jesus Christ to be whole. She was healed immediately and could lift and use her arm; the next day she was able to do chores, including washing. When Ezra Booth asked whether her arm was healed, she reportedly straightened it and said, “It is as good as the other.” One account also says the event was witnessed by a Campbellite physician and a Methodist preacher. The accounts differ in some details of the location and timing: one describes the healing at the Whitney home in Kirtland, while another places it in Hiram after the Johnsons had stayed at the Whitney home in Kirtland.

Fuller account of this event (as retold in Amos S. Hayden, Early History of the Disciples in the Western Reserve, Ohio (1875), as cited in Joseph Smith Foundation, 'Joseph Smith - Miracles'):

Ezra Booth, of Mantua, a Methodist preacher of much more than ordinary culture, and with strong natural abilities, in company with his wife, Mr. and Mrs. Johnson, and some other citizens of this place, (Hiram) visited Smith at his home in Kirtland, in 1831. Mrs. Johnson had been afflicted for some time with a lame arm, and was not at the time of the visit able to lift her hand to her head. The party visited Smith partly out of curiosity, and partly to see for themselves what there might be in the new doctrine. Johnson with a lame arm; has God given any power to men now on earth to cure her? A few moments later, when the conversation had turned in another direction, Smith arose, and walking across the room, and taking Mrs. Johnson by the hand, said in the most solemn and impressive manner: “Woman, in the name of the Lord Jesus Christ, I command thee to be whole,” and immediately left the room. The company were awe-stricken at the infinite presumption of the man, and the calm assurance with which he spoke. The sudden mental and moral shock—I know not how better to explain the well-attested fact—electrified the rheumatic arm—Mrs. Johnson at once lifted it with ease, and on her return home the next day she was able to do her washing without difficulty or pain.
