Actually “prophesy” is a gift from the Holy Spirit mentioned in the New Testament—a sign that the Kingdom of God has come (I Cor. 14; Act 2:17,18; 13:9; 19:6). St. Paul was warned by the prophet Agabus in Acts (11:28; 21:10). Was Apostle Paul mislead by a “B.S. artist?”
St. John wrote the book of Revelation...probably around AD 100...it is full of prophesies—in fact, it is THE most prophetic book in the Bible. Was John just a B.S. artist?
A prophet in the biblical sense is an extra-special man of God whom, you are correct, receives direct revelation from God. Often (but not always) those revelations were written down. All prophets were...of impeccable character.
There was a great famine of prophets and prophesy...a silence if you will, of around 400 years, from Zachariah to John the Baptist—who, most Bible scholars recognize was the last of the Old Testament style prophets—who communicated the revelation from God that His Kingdom was near—and—John testified as to the Kingship of Jesus Christ.
All of the Apostles, in that sense, were prophets—as they received the ULTIMATE revelation from God—Himself, in the person of Jesus Christ. Of course they wrote down their Holy Spirit inspired writings—in what we now know as the New Testament.
That canon is closed however...and no orthodox Christian has maintained anyone, anywhere at any time has the authority to add to the Bible—the prophetic testimony of the eyewitnesses of the resurrection.
A part of the Jewish bible was called “The Prophets” and, the traditionally recognized prophets were, in New Testament times...from the distant past—as the book of Hebrews shows. However, Jesus Himself, in His role as PROPHET, Priest and King, was indeed, the ultimate Prophet...
Jesus’ designated spokesmen—and eyewitnesses to His resurrection—were the Apostles—and, as mentioned above, they too, were “prophets” as receivers and communicators of direct revelation from God. Their testimony IS the New Testament.
Was Joseph Smith a prophet-from-God? Absolutely not. Many proofs are available of that...but, the easiest is to show that St. Paul made an absolute requirement that ALL Church leaders be the “husband of one wife.” (I Tim 3, Titus 1)
The fact alone that Joseph Smith flagrantly violated St. Paul’s command for monogamy...and taught others to do likewise, proves, very simply, he was a false prophet, a man of terrible character—NOT from God.
THE BOOK OF JACOB
THE BROTHER OF NEPHICHAPTER 224 Behold, David and Solomon truly had many wives and concubines, which thing was abominable before me, saith the Lord.
25 Wherefore, thus saith the Lord, I have led this people forth out of the land of Jerusalem, by the power of mine arm, that I might raise up unto me a righteous branch from the fruit of the loins of Joseph.
26 Wherefore, I the Lord God will not suffer that this people shall do like unto them of old.
27 Wherefore, my brethren, hear me, and hearken to the word of the Lord: For there shall not any man among you have save it be one wife; and concubines he shall have none;
28 For I, the Lord God, delight in the chastity of women. And whoredoms are an abomination before me; thus saith the Lord of Hosts.
29 Wherefore, this people shall keep my commandments, saith the Lord of Hosts, or cursed be the land for their sakes.
30 For if I will, saith the Lord of Hosts, raise up seed unto me, I will command my people; otherwise they shall hearken unto these things.
31 For behold, I, the Lord, have seen the sorrow, and heard the mourning of the daughters of my people in the land of Jerusalem, yea, and in all the lands of my people, because of the wickedness and abominations of their husbands.
32 And I will not suffer, saith the Lord of Hosts, that the cries of the fair daughters of this people, which I have led out of the land of Jerusalem, shall come up unto me against the men of my people, saith the Lord of Hosts.

1 Timothy 3:2-3
2. Now the overseer must be above reproach, the husband of but one wife, temperate, self-controlled, respectable, hospitable, able to teach,
3. not given to drunkenness, not violent but gentle, not quarrelsome, not a lover of money.1 Timothy 3:12
A deacon must be the husband of but one wife and must manage his children and his household well.Titus 1:6
An elder must be blameless, the husband of but one wife, a man whose children believe and are not open to the charge of being wild and disobedient.
THE
DOCTRINE AND COVENANTS
OF THE CHURCH OF JESUS CHRIST OF LATTER-DAY SAINTSSECTION 13251–57, Emma Smith is counseled (commanded) to be faithful and true; 58–66, Laws governing the plurality of wives are set forth.51 Verily, I say unto you: A commandment I give unto mine handmaid, Emma Smith, your wife, whom I have given unto you, that she stay herself and partake not of that which I commanded you to offer unto her; for I did it, saith the Lord, to aprove you all, as I did Abraham, and that I might require an offering at your hand, by covenant and sacrifice.52 And let mine handmaid, Emma Smith, areceive all those that have been given unto my servant Joseph, and who are virtuous and pure before me; and those who are not pure, and have said they were pure, shall be destroyed, saith the Lord God.53 For I am the Lord thy God, and ye shall obey my voice; and I give unto my servant Joseph that he shall be made ruler over many things; for he hath been afaithful over a few things, and from henceforth I will strengthen him.55 But if she will not abide this commandment, then shall my servant Joseph do all things for her, even as he hath said; and I will bless him and multiply him and give unto him an ahundredfold in this world, of fathers and mothers, brothers and sisters, houses and lands, wives and children, and crowns of beternal lives in the eternal worlds.
