Daniel sees four beasts representing the kingdoms of men—He sees the ancient of days (Adam) to whom the Son of Man (Christ) will come—The kingdom will be given to the Saints forever.
The Holy Bible, Daniel 7:9-10,13-14
9 I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire.
10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened.
13 I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him.
14 And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed.

Elder Joseph Fielding Smith said that the council at Adam-ondi-Ahman, as prophesied in Daniel 7:9-14, will be of the greatest importance to this world. At that time there will be a transfer of authority from the usurper and impostor, Lucifer, to the rightful King, Jesus Christ. Judgment will be set and all who have held keys will make their reports and deliver their stewardships, as they shall be required. Adam will direct this judgment, and then he will make his report, as the one holding the keys for this earth, to his Superior Officer, Jesus Christ. Our Lord will then assume the reins of government; directions will be given to the Priesthood; and He, whose right it is to rule, will be installed officially by the voice of the Priesthood there assembled. This grand council of Priesthood will be composed, not only of those who are faithful who now dwell on this earth, but also of the prophets and apostles of old, who have had directing authority. Others may also be there, but if so they will be there by appointment, for this is to be an official council called to attend to the most momentous matters concerning the destiny of this earth. When this gathering is held, the world will not know of it; the members of the Church at large will not know of it, yet it shall be preparatory to the coming in the clouds of glory of our Savior Jesus Christ as the Prophet Joseph Smith has said. The world cannot know of it. The Saints cannot know of it—except those who officially shall be called into this council—for it shall precede the coming of Jesus Christ as a thief in the night, unbeknown to all the world. (Way to Perfection, pp. 290-91.)
History of the Church, Joseph Smith 3:386
Daniel in his seventh chapter speaks of the Ancient of Days; he means the oldest man, our Father Adam, Michael, he will call his children together and hold a council with them to prepare them for the coming of the Son of Man. He (Adam) is the father of the human family, and presides over the spirits of all men, and all that have had the keys must stand before him in this grand council. This may take place before some of us leave this stage of action. The Son of Man stands before him, and there is given him glory and dominion. Adam delivers up his stewardship to Christ, that which was delivered to him as holding the keys of the universe, but retains his standing as head of the human family.
Journal of Discourses, Orson Pratt 17:29
I say we are told by this Prophet that the Ancient of days is the most ancient personage that ever had an existence in days here on the earth. And who was he? Why, of course, old father Adam, he was the most ancient man that ever lived in days that we have any knowledge of. He comes, then, as a great judge, to assemble this innumerable host of which Daniel speaks. He comes in flaming fire. The glory and blessing and greatness of this personage it would be impossible even for a man as great as Daniel fully to describe. He comes as a man inspired from the eternal throne of Jehovah himself. He comes to set in order the councils of the Priesthood pertaining to all dispensations, to arrange the Priesthood and the councils of the Saints of all former dispensations in one grand family and household. What is all this for? Why all this arrangement? Why all this organization? Why all this judgment and the opening of the books? It is to prepare the way for another august personage whom Daniel saw coming with the clouds of heaven, namely the Son of Man, and these clouds of heaven brought the Son of Man near before the Ancient of days. And when the Son of Man came to the Ancient of days, behold a kingdom was given to the Son of Man, and greatness and glory, that all people, nations and languages should serve him, and his kingdom should be an everlasting kingdom, a kingdom that should never be done away.
