Ether 5

I write to the person [Joseph Smith, Jr. ] who will be lead by the Lord in the last days to these records. Moriancumer’s words are sealed shut. Do not touch them; it is not allowed. You may be allowed to show these gold plates to a few persons who help you. Three men will be shown the plates by God’s power. They will know these things are true. All things will be established by three witnesses.
