All prophets who had glorious visions, first recieved the Second Comforter.
"Now what is this other Comforter? It is no more nor less than the Lord Jesus Christ Himself; and this is the sum and substance of the whole matter; that when any man obtains this last Comforter, he will have the personage of Jesus Christ to attend him, or appear unto him from time to time, and even He will manifest the Father unto him, and they will take up their abode with him, and the visions of the heavens will be opened unto him, and the Lord will teach him face to face, and he may have a perfect knowledge of the mysteries of the Kingdom of God; and this is the state and place the ancient Saints arrived at when they had such glorious visions--Isaiah, Ezekiel, John upon the Isle of Patmos, St. Paul in the three heavens, and all the Saints who held communion with the general assembly and Church of the Firstborn." (TPJS Section 3, p. 151)
Isaiah
"In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple. Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly. And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory. And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.
"Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts." (Isaiah 6:1-5)
Isaiah's Wife
"And I went unto the prophetess; and she conceived, and bare a son." (Isaiah 8:3)
Mormon
"And I, being fifteen years of age and being somewhat of a sober mind, therefore I was visited of the Lord, and tasted and knew of the goodness of Jesus." (Mormon 1:15)
Nephi
"And now I, Nephi, write more of the words of Isaiah, for my soul delighteth in his words. For I will liken his words unto my people, and I will send them forth unto all my children, for he verily saw my Redeemer, even as I have seen him. And my brother, Jacob, also has seen him as I have seen him." (2 Nephi 11:3-4)
Jacob (brother of Nephi)
"I know that thou art redeemed, because of the righteousness of thy Redeemer; for thou hast beheld that in the fulness of time he cometh to bring salvation unto men. And thou hast beheld in thy youth his glory; wherefore, thou art blessed even as they unto whom he shall minister in the flesh; for the Spirit is the same, yesterday, today, and forever. And the way is prepared from the fall of man, and salvation is free." (2 Nephi 2:3-4)
"And now I, Nephi, write more of the words of Isaiah, for my soul delighteth in his words. For I will liken his words unto my people, and I will send them forth unto all my children, for he verily saw my Redeemer, even as I have seen him. And my brother, Jacob, also has seen him as I have seen him." (2 Nephi 11:3-4)
Lamoni
"For as sure as thou livest, behold, I have seen my Redeemer; and he shall come forth, and be born of a woman, and he shall redeem all mankind who believe on his name. Now, when he had said these words, his heart was swollen within him, and he sunk again with joy; and the queen also sunk down, being overpowered by the Spirit." (Alma 19:13)
Lamoni's Wife
"And it came to pass that she went and took the queen by the hand, that perhaps she might raise her from the ground; and as soon as she touched her hand she arose and stood upon her feet, and cried with a loud voice, saying: O blessed Jesus, who has saved me from an awful hell!" (Alma 19:29)
