Joseph of Egypt prophesies of a spokesman being appointed for the "Moses" who will translate the plates of the Book of Mormon.
2 Nephi 3:17-18, Book of Mormon, The Church of Jesus Christ of Latter-day Saints, accessed July 23, 2024
17 And the Lord hath said: I will raise up a Moses; and I will give power unto him in a rod; and I will give judgment unto him in writing. Yet I will not loose his tongue, that he shall speak much, for I will not make him mighty in speaking. But I will write unto him my law, by the finger of mine own hand; and I will make a spokesman for him.
18 And the Lord said unto me also: I will raise up unto the fruit of thy loins; and I will make for him a spokesman. And I, behold, I will give unto him that he shall write the writing of the fruit of thy loins, unto the fruit of thy loins; and the spokesman of thy loins shall declare it.
