12 But, behold, they shall have wars, and rumors of wars; and when the day cometh that the Only Begotten of the Father, yea, even the Father of heaven and of earth, shall manifest himself unto them in the flesh, behold, they will reject him, because of their iniquities, and the hardness of their hearts, and the stiffness of their necks.
 13 Behold, they will crucify him; and after he is laid in a sepulchre for the space of three days he shall rise from the dead, with healing in his wings; and all those who shall believe on his name shall be saved in the kingdom of God. Wherefore, my soul delighteth to prophesy concerning him, for I have seen his day, and my heart doth magnify his holy name.
 14 And behold it shall come to pass that after the Messiah hath risen from the dead, and hath manifested himself unto his people, unto as many as will believe on his name, behold, Jerusalem shall be destroyed again; for wo unto them that fight against God and the people of his church.
 15 Wherefore, the Jews shall be scattered among all nations; yea, and also Babylon shall be destroyed; wherefore, the Jews shall be scattered by other nations.
 16 And after they have been scattered, and the Lord God hath scourged them by other nations for the space of many generations, yea, even down from generation to generation until they shall be persuaded to believe in Christ, the Son of God, and the atonement, which is infinite for all mankind—and when that day shall come that they shall believe in Christ, and worship the Father in his name, with pure hearts and clean hands, and look not forward any more for another Messiah, then, at that time, the day will come that it must needs be expedient that they should believe these things.
 17 And the Lord will set his hand again the second time to restore his people from their lost and fallen state. Wherefore, he will proceed to do a marvelous work and a wonder among the children of men.
 18 Wherefore, he shall bring forth his words unto them, which words shall judge them at the last day, for they shall be given them for the purpose of convincing them of the true Messiah, who was rejected by them; and unto the convincing of them that they need not look forward any more for a Messiah to come, for there should not any come, save it should be a false Messiah which should deceive the people; for there is save one Messiah spoken of by the prophets, and that Messiah is he who should be rejected of the Jews.
 19 For according to the words of the prophets, the Messiah cometh in six hundred years from the time that my father left Jerusalem; and according to the words of the prophets, and also the word of the angel of God, his name shall be Jesus Christ, the Son of God.  2 Nephi 25:12-19

This prophecy by Nephi in the Book of Mormon, supposedly written around 550 BC, conveys more accurate prophecies than any other section of the Bible.  Prophecies such as:

• God is going to send his son (Old Testament never communicates clearly the Father-Son relationship of the Trinity, that's why the Pharisees could not accept such a concept)
• This son of God will come in the flesh (The Jews were looking for a Messiah more along the lines of a Moses or Elijah)
• He will be crucified (Isaiah gives imagery of crucifixion, but since crucifixions were not popular in 600 BC, they were not known as "crucifixion")
• This son will rise out of the grave after days (only Jesus says this to his followers)
• Those who believe in his name will be saved
• Jerusalem will be destroyed again, apparently they are speaking of 70 AD (a point that is not clearly stated until Jesus and the apostle John speak of it)
• Jews will be scattered (this is an Old Testament prophecy)
• "Christ, Son of God" (Peter was the first to say this in Matthew 16:16)
• This Messiah will be the one and only true Messiah, spoken of by the prophets and he will be rejected by the Jews (OT alludes to a cornerstone rejected by the builders, but it is not clearly understood until Matthew 21:42)
• This Messiah will show 600 years from when Nephi's family left Jerusalem, precisely when Jesus appeared on earth. (This is a remarkably accurate prophecy)
• His name will be Jesus, the Son of God (the angel Gabriel was the first to announce his name in Matthew 1:21, nine months before Jesus was born)

These prophecies could only be conceived by someone on the other side of Jesus' return.  If this prophecy had been known by the Pharisees, they would have accepted Jesus more readily.

Why would God hide this prophecy with a mysterious tribe in Israel?  He would certainly make the information clearer so more would accept him.
