He quoted ancient prophets who had foreseen that this time would come. As Moroni stood before him, Joseph was shown in vision “the place where the plates were deposited” (Joseph Smith—History 1:42).
He quoted ancient prophets who had foreseen that this time would come. Moroni explained that "a history of the aborigines of this country... was written and deposited not far from" Joseph's home, and that "the record is on a side hill on the Hill of Cumorah 3 miles from this place." 5 As Moroni stood before him, Joseph was shown in vision “the place where the plates were deposited” (Joseph Smith—History 1:42).

Every September for four years, Joseph went to the Hill Cumorah and was taught by Moroni. In September 1827 Joseph met Moroni at the hill and received the gold plates. Twenty-one months later, having completed the translation, Joseph returned the plates to Moroni.5
Every September for three years, Joseph went to the Hill Cumorah and was taught by Moroni. In early 1827, Joseph came home late from Manchester and explained to his concerned parents that "as I passed by the hill of Cumorah, where the plates are, the angel of the Lord met me and said, that I had not been engaged enough in the work of the Lord; that the time had come for the record to be brought forth."6 In September 1827 Joseph met Moroni at the hill and received the gold plates. When he finished the translation, Joseph returned the plates to Moroni.7

Joseph Smith Quotes
“This messenger [Moroni] proclaimed himself to be an angel of God, sent to bring the joyful tidings that the covenant which God made with ancient Israel was at hand to be fulfilled, that the preparatory work for the second coming of the Messiah was speedily to commence; that the time was at hand for the Gospel in all its fullness to be preached in power, unto all nations that a people might be prepared for the Millennial reign. I was informed that I was chosen to be an instrument in the hands of God to bring about some of His purposes in this glorious dispensation” (History of the Church, 4:536–37).

“Let us take the Book of Mormon, which a man took and hid in his field, securing it by his faith, to spring up in the last days, or in due time; let us behold it coming forth out of the ground, which is indeed accounted the least of all seeds, but behold it branching forth, yea, even towering, with lofty branches, and God-like majesty, until it, like the mustard seed, becomes the greatest of all herbs. And it is truth, and it has sprouted and come forth out of the earth, and righteousness begins to look down from heaven, and God is sending down His powers, gifts and angels, to lodge in the branches thereof” (Teachings of the Prophet Joseph Smith, sel. Joseph Fielding Smith (1976), 98).

Witnesses
Joseph Knight, Early Member of the Church
“[In] the forepart of September [1827,] I went to Rochester on business and returned by Palmyra to be there about the 22nd of September. . . . That night we all went to bed and in the morning I got up and my horse and carriage were gone. . . . After a while he [Joseph Smith] came home [with] the horse. All came into the house to breakfast. But no thing [was] said about where they had been. After breakfast Joseph called me into the other room. . . . He set his foot on the bed and leaned his head on his hand and said, . . . ‘It is ten times better than I expected.’ Then he went on to tell the length and width and thickness of the plates, and said he, ‘They appear to be gold’” (Reminiscenses of Joseph Knight, Church History Library, Salt Lake City; spelling, grammar, and capitalization standardized. This manuscript, written between 1833 and 1847, has been published in Dean C. Jessee, “Joseph Knight’s Recollection of Early Mormon History,” BYU Studies, vol. 17, no. 1 [Fall 1976], 30–39).
John A. Widtsoe, Apostle, 1921–1952
“The first visitation of Moroni came in answer to prayer. So came the First Vision. The Lord is ready to give, but he requires that his children ask. It would not be natural or wise to force blessings on anyone. The power of prayer is inestimable. One prays for little; usually much comes in answer. . . . The most marvelous part of the message to the young man, lying upon his wakeful pillow, was that he, Joseph Smith, was the chosen instrument in the hands of the Lord to inaugurate the great work planned for the last days of the world. It was astonishing! It was wonderful!” (Joseph Smith: Seeker after Truth, Prophet of God [1951], 32–33; paragraph divisions altered).
Questions
How many times did Moroni visit the Prophet Joseph?
There is no record of the exact number of visits from Moroni, but 22 have been documented (see H. Donl Peterson, “Moroni—Joseph Smith’s Tutor,” Ensign, Jan. 1992, 22–29).
What did Joseph Smith learn in his visits with Moroni?
Moroni taught Joseph Smith from scripture, quoting Malachi, Isaiah, Joel, and Acts. John Taylor explained: “Joseph Smith in the first place was set apart by the Almighty according to the [councils] of the Gods in the eternal worlds, to introduce the principles of life among the people. . . . The principles which he had, placed him in communication with . . . Abraham, Isaac, Jacob, Noah, Adam, Seth, Enoch, and Jesus and the Father and the apostles that lived on this continent as well as those who lived on the Asiatic continent. . . . Why? Because he had to introduce a dispensation which was called the dispensation of the fulness of times, and it was known as such by the ancient servants of God” (Deseret News, June 9, 1880, 280).
What did Moroni teach Joseph Smith about the ancient Americans?
Joseph also learned about the ancient inhabitants of the Americas, “who they were, and from whence they came; a brief sketch of their origin, progress, civilization, laws, governments, of their righteousness and iniquity, and the blessings of God being finally withdrawn from them as a people” (History of the Church, 4:537).
