Joseph Smith - Matthew

In the closing days of His ministry, the Savior said to His disciples -

"...that ye shall not see me henceforth and know that I am he of whom it is written by the prophets, until ye shall say: Blessed is he who cometh in the name of the Lord, in the clouds of heaven, and all the holy angels with him. Then understood his disciples that he should come again on the earth, after that he was glorified and crowned on the right hand of God." (Pearl of Great Price JS-Matthew 1:1)

Throughout scripture the prophets have testified that Christ would come again. The following are just a few -

"For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth..." Old Testament Job 19:25)

"When the LORD shall build up Zion, he shall appear in his glory." (Old Testament Psalms 102:16)

"...the glory of the LORD shall be revealed, and all flesh shall see it together..." (Old Testament Isaiah 40:5)

"I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven..." (Old Testament Daniel 7:13)

"...behold, the LORD cometh forth out of his place, and will come down, and tread upon the high places of the earth." (Old Testament Micah 1:3)

"...one shall say unto him, What are these wounds in thine hands? Then he shall answer, Those with which I was wounded in the house of my friends." (Old Testament Zechariah 13:6)

"...the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.
2 But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fullers' soap..." (Old Testament Malachi 3:1 - 2)

Nephi told the corrupt judges of other Old Testament prophets saying -

"...behold, Moses did not only testify of these things, but also all the holy prophets, from his days even to the days of Abraham.
17 Yea, and behold, Abraham saw of his coming, and was filled with gladness and did rejoice.
18 Yea, and behold I say unto you, that Abraham not only knew of these things, but there were many before the days of Abraham who were called by the order of God; yea, even after the order of his Son; and this that it should be shown unto the people, a great many thousand years before his coming, that even redemption should come unto them.
19 And now I would that ye should know, that even since the days of Abraham there have been many prophets that have testified these things; yea, behold, the prophet Zenos did testify boldly; for the which he was slain.
20 And behold, also Zenock, and also Ezias, and also Isaiah, and Jeremiah, (Jeremiah being that same prophet who testified of the destruction of Jerusalem) and now we know that Jerusalem was destroyed according to the words of Jeremiah. O then why not the Son of God come, according to his prophecy?
21 And now will you dispute that Jerusalem was destroyed? Will ye say that the sons of Zedekiah were not slain, all except it were Mulek? Yea, and do ye not behold that the seed of Zedekiah are with us, and they were driven out of the land of Jerusalem? But behold, this is not all—
22 Our father Lehi was driven out of Jerusalem because he testified of these things. Nephi also testified of these things, and also almost all of our fathers, even down to this time; yea, they have testified of the coming of Christ, and have looked forward, and have rejoiced in his day which is to come.
23 And behold, he is God, and he is with them, and he did manifest himself unto them, that they were redeemed by him; and they gave unto him glory, because of that which is to come." (Book of Mormon Helaman 8:16 - 23)

Peter also said -

"...he shall send Jesus Christ, which before was preached unto you:
21 Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
22 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you.
23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
24 Yea, and all the prophets from Samuel and those that follow after, as many as have spoken, have likewise foretold of these days." (New Testament Acts 3:20 - 24)

And later wrote that -

"...the day of the Lord will come as a thief in the night..." (New Testament 2 Peter 3:10)

Paul also wrote -

"...this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air..." (New Testament 1 Thessalonians 4:15 - 17)

And the Lord said to John the Revelator -

"...behold, I come quickly..." (New Testament Revelation 22:12)

These are but a few ancient prophecies of the coming of the Lord.
