Isaiah 29: 4 "And thou shalt be brought down, and shalt speak out of the ground, and thy speech shall be low out of the dust, and thy voice shall be, as of one that hath a familiar spirit, out of the ground, and thy speech shall whisper out of the dust." [The Book of Mormon came "out of the ground" and in it, the Nephites, our dead Israelite "relatives" who came from Ariel; in other words, Jerusalem, speaks to us as from the dust.]
Isaiah 29:11-12, 14 "And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed: And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned. ...Therefore, behold, I will proceed to do a marvellous work among this people, even a marvellous work and a wonder: for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid." [Isaiah gives prophecy about the coming forth of the Book of Mormon in the last days. He gives specific detail which has been fulfilled.]
Joseph Smith--History 1:63-65 "Sometime in this month of February, the aforementioned Mr Martin Harris came to our place, got the characters which I had drawn off the plates, and started with them to the city of New York. For what took place relative to him and the characters, I refer to his own account of the circumstances, as he related them to me after his return, which was as follows: "I went to the city of New York, and presented the characters which had been translated, with the translation thereof, to Professor Charles Anthon, a gentleman celebrated for his literary attainments. Professor Anthon stated that the translation was correct, more so than any he had before seen translated from the Egyptian. I then showed him those which were not yet translated, and he said that they were true characters. He gave me a certificate, certifying to the people of Palmyra that they were true characters, and that the translation of such of them as had been translated was also correct. I took the certificate and put it into my pocket, and was just leaving the house, when Mr Anthon called me back, and asked me how the young man found out that there were gold plates in the place where he found them. I answered that an angel of God had revealed it unto him. He then said to me, 'Let me see that certificate.' I accordingly took it out of my pocket and gave it to him, when he took it and tore it to pieces, saying that there was no such thing now as ministering of angels, and that if I would bring the plates to him he would translate them. I informed him that part of the plates were sealed, and that I was forbidden to bring them. He replied, 'I cannot read a sealed book.' I left him and went to Dr Mitchell, who sanctioned what Professor Anthon had said respecting both the characters and the translation.""
