I stumbled upon the following quotation from President Hinckley from a 1984 talk:
He then went on to say to Emma, “Murmur not because of the things which thou hast not seen.” (D&C 25:4.) He was speaking of the plates which her husband was translating, she serving at the time as his scribe. Evidently she complained because Joseph would not show them to her. The Lord is saying to her, “Murmur not. Complain not. Accept what must be in my eternal wisdom, and do not find fault.” There are a few women in the Church who complain because they do not hold the priesthood. I think the Lord would say to you, “murmur not because of the things which are not given thee.”
This is his work. Joseph did not set the rule about not showing the plates to others. He was instructed concerning it. Nor have we set the rule concerning those who should receive the priesthood. That was established by him whose work this is, and he alone could change it.
Emma was called, in the words of this revelation, to be “a comfort unto my servant, Joseph Smith, Jun., thy husband, in his afflictions, with consoling words, in the spirit of meekness.” (D&C 25:5.) That is interesting language. She was his wife, his companion, his strength in his afflictions. She was to comfort with consoling words, given in a spirit of meekness.
I see in that the challenge to every woman who is a wife to set the tone of that which is spoken in the home. It was said of old that “a soft answer turneth away wrath.” (Prov. 15:1.) It is interesting to me that in this revelation the Lord spoke of consoling words in the spirit of meekness.
