The Holy Bible, Deuteronomy 30:1-5

1 And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call them to mind among all the nations, whither the Lord thy God hath driven thee,

2 And shalt return unto the Lord thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul;

3 That then the Lord thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the Lord thy God hath scattered thee.

4 If any of thine be driven out unto the outmost parts of heaven, from thence will the Lord thy God gather thee, and from thence will he fetch thee:

5 And the Lord thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers.

The Holy Bible, Isaiah 11:15-16

15 And the Lord shall utterly destroy the tongue of the Egyptian sea; and with his mighty wind shall he shake his hand over the river, and shall smite it in the seven streams, and make men go over dryshod.

16 And there shall be an highway for the remnant of his people, which shall be left, from Assyria; like as it was to Israel in the day that he came up out of the land of Egypt.

The Holy Bible, Isaiah 51:11,14

11 Therefore the redeemed of the Lord shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.

14 The captive exile hasteneth that he may be loosed, and that he should not die in the pit, nor that his bread should fail.

The Holy Bible, Isaiah 54:1-3

1 Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for more are the children of the desolate than the children of the married wife, saith the Lord.

2 Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;

3 For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.

The Holy Bible, Jeremiah 16:13-15

13 Therefore will I cast you out of this land into a land that ye know not, neither ye nor your fathers; and there shall ye serve other gods day and night; where I will not shew you favour.

14 Therefore, behold, the days come, saith the Lord, that it shall no more be said, The Lord liveth, that brought up the children of Israel out of the land of Egypt;

15 But, The Lord liveth, that brought up the children of Israel from the land of the north, and from all the lands whither he had driven them: and I will bring them again into their land that I gave unto their fathers. 16 Behold, I will send for many fishers, saith the Lord, and they shall fish them; and after will I send for many hunters, and they shall hunt them from every mountain, and from every hill, and out of the holes of the rocks.

The Holy Bible, Jeremiah 31:8-9

8 Behold, I will bring them from the north country, and gather them from the coasts of the earth, and with them the blind and the lame, the woman with child and her that travaileth with child together: a great company shall return thither.

9 They shall come with weeping, and with supplications will I lead them: I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble: for I am a father to Israel, and Ephraim is my firstborn.

The Book of Mormon, 2 Nephi 29:13

13 And it shall come to pass that the Jews shall have the words of the Nephites, and the Nephites shall have the words of the Jews; and the Nephites and the Jews shall have the words of the lost tribes of Israel; and the lost tribes of Israel shall have the words of the Nephites and the Jews.

The Book of Mormon, 3 Nephi 17:4

4 But now I go unto the Father, and also to show myself unto the lost tribes of Israel, for they are not lost unto the Father, for he knoweth whither he hath taken them.

The Book of Mormon, 3 Nephi 21:24-26

24 And then shall they assist my people that they may be gathered in, who are scattered upon all the face of the land, in unto the New Jerusalem.

25 And then shall the power of heaven come down among them; and I also will be in the midst.

26 And then shall the work of the Father commence at that day, even when this gospel shall be preached among the remnant of this people. Verily I say unto you, at that day shall the work of the Father commence among all the dispersed of my people, yea, even the tribes which have been lost, which the Father hath led away out of Jerusalem.

The Doctrine and Covenants, Section 110:11

11 After this vision closed, the heavens were again opened unto us; and Moses appeared before us, and committed unto us the keys of the gathering of Israel from the four parts of the earth, and the leading of the ten tribes from the land of the north.

The Doctrine and Covenants, Section 133:26-34

26 And they who are in the north countries shall come in remembrance before the Lord; and their prophets shall hear his voice, and shall no longer stay themselves; and they shall smite the rocks, and the ice shall flow down at their presence.

27 And an highway shall be cast up in the midst of the great deep.

28 Their enemies shall become a prey unto them,

29 And in the barren deserts there shall come forth pools of living water; and the parched ground shall no longer be a thirsty land.

30 And they shall bring forth their rich treasures unto the children of Ephraim, my servants.

31 And the boundaries of the everlasting hills shall tremble at their presence.

32 And there shall they fall down and be crowned with glory, even in Zion, by the hands of the servants of the Lord, even the children of Ephraim.

33 And they shall be filled with songs of everlasting joy.

34 Behold, this is the blessing of the everlasting God upon the tribes of Israel, and the richer blessing upon the head of Ephraim and his fellows.

The Doctrine and Covenants, Section 77:14

14 Q. What are we to understand by the little book which was eaten by John, as mentioned in the 10th chapter of Revelation? A. We are to understand that it was a mission, and an ordinance, for him to gather the tribes of Israel; behold, this is Elias, who, as it is written, must come and restore all things.

The Pearl of Great Price, Articles of Faith 1:10

10 We believe in the literal gathering of Israel and in the restoration of the Ten Tribes; that Zion (the New Jerusalem) will be built upon the American continent; that Christ will reign personally upon the earth; and, that the earth will be renewed and receive its paradisiacal glory.

Conference Report, James E. Talmage, April 1916

There is a tendency among men to explain away what they don’t wish to understand in literal simplicity, and we, as Latter-day Saints are not entirely free from the taint of that tendency. Prophecies that have not yet been fulfilled are by many of us made the subjects of hypothesis and theory and strained interpretation. We read that one of the characteristic signs to precede the second advent of Christ shall be the bringing forth of the tribes that have been lost to history, led away where men have not yet found them, and we are told that they shall be brought forth with a strong hand by the power of God and shall come unto Zion and receive their blessings at the hands of Ephraim. But some people say that prediction is to be explained in this way: A gathering is in progress, and has been in progress from the early days of this Church; and thus the “Lost Tribes” are now being gathered; but that we are not to look for the return of any body of people now unknown as to their whereabouts. True, the gathering is in progress, this is a gathering dispensation; but the prophecy stands that the tribes shall be brought forth from their hiding place bringing their scriptures with them, which scriptures shall become one with the scriptures of the Jews, the holy Bible, and with the scriptures of the Nephites, the Book of Mormon, and with the scriptures of the Latter-day Saints as embodied in the volumes of modern revelation.

Conference Report, James E. Talmage, October 1916

I have found elders in Israel who would tell me that the predictions relating to the Lost Tribes are to be explained in this figurative manner–that the gathering of those tribes is already well advanced and that there is no hiding place whereto God has led them, from which they shall come forth, led by their prophets to receive their blessings here at the hands of gathered Ephraim, the gathered portions that have been scattered among the nations. Yea, let God be true, and doubt we not his word, though it makes the opinions of men appear to be lies. The tribes shall come; they are not lost unto the Lord; they shall be brought forth as hath been predicted; and I say unto you there are those now living–aye, some here present–who shall live to read the records of the Lost Tribes of Israel, which shall be made one with the record of the Jews, or the Holy Bible, and the record of the Nephrites, or the Book of Mormon, even as the Lord hath predicted; and those records, which the tribes lost to man but yet to be found again shall bring, shall tell of the visit of the resurrected Christ to them, after He had manifested Himself to the Nephites upon this continent. For, as not one jot or tittle of the Law has been permitted to fail, so surely no jot or tittle of the Gospel shall go unfulfilled.

Conference Report, John H. Taylor, October 1937

Criticism may be helpful or detrimental, helpful if it increases our knowledge of the revealed word, detrimental when it insists on an interpretation that is not in harmony with the whole message of the book or the accepted doctrine of the Church. For instance, a man said to me the other day : “Do you know where the Lost Tribes are?” I said: “Well, no, I do not know where they are.” “Well,” he said, “do you think they are at the North Pole?” I said: “No, I do not know if they are up at the North Pole.” (Of course the Russians and others were flying back and forth.) “Do you think they are down to the South Pole ?” I told him, “No, I think perhaps they are not there.” He said : “Do you think they are up in some star or some other place?” I said: “I do not know where they are. All that I can tell you is what President Grant has said—that they are lost.” “Well,” he said to me, “I do not think they are lost. They are found.” Then he made the explanation that they are all safely located over in Europe, and that they are gathering here in Zion and bringing their records with them. (He was referring to their genealogical records.) I might have argued, “I understood that the ice was going to flow down in their presence when they came forth.” Likely he would have answered, “But the ice is flowing down from the north all the time.” Then I thought of the idea that if Christ left his message in Jerusalem, along with a written record by his disciples of his life and teachings, and then came to America and left his message here, and the Indians had a record and a tradition still existing among them concerning the visit of the Christ, undoubtedly the Lost Tribes whom Christ said he was going to visit would at least have a tradition about his visit among them and also, I believe, a written record as in the other two cases. Well, that thought is going the rounds. We are not satisfied to leave things as they are and wait for additional revelation from the Lord. To many it is embarrassing to talk about a lost people when to all appearances the earth has been thoroughly explored. In order to harmonize an apparent discrepancy, we assume an explanation instead of waiting for revelation on the subject. This bewilders people and makes them think that perhaps Joseph Smith was wrong in his statement concerning the Ten Tribes.

History of the Church, Joseph Smith 1:176

The Spirit of the Lord fell upon Joseph in an unusual manner, and he prophesied that John the Revelator was then among the Ten Tribes of Israel who had been led away by Shalmaneser, king of Assyria, to prepare them for their return from their long dispersion, to again possess the land of their fathers. —Quote by John Whitmer

History of the Church, Joseph Smith 1:315

And now I am prepared to say by the authority of Jesus Christ, that not many years shall pass away before the United States shall present such a scene of bloodshed as has not a parallel in the history of our nation; pestilence, hail, famine, and earthquake will sweep the wicked of this generation from off the face of the land, to open and prepare the way for the return of the lost tribes of Israel from the north country.

Journal of Discourses, Orson Pratt 14:9

But as a still further testimony of the power that will be made manifest in the restitution of Israel, let me refer you to another passage, which is contained in the 11th chapter of Isaiah, “He shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.” Here is a declaration that the two great kingdoms of Israel–its “outcasts,” the ten tribes, scattered seven hundred and twenty years before Christ, and the “dispersed of Judah,” dispersed among all nations, shall be gathered. But before he gathers them he will set up an ensign–an ensign is to be raised in the latter days especially for the gathering of Israel. Again, says the Prophet, “And the Lord shall utterly destroy the tongue of the Egyptian sea.” How? “With his mighty power shall he shake his hand over the river and shall smite it in the seven streams and make men go over dry-shod. And there shall be an highway for the remnant of his people which shall be left, from Assyria like as it was to Israel in the day that he came up out of the land of Egypt.” The same thing, not a spiritual, but a literal transaction, as the Lord smote the tongue of the Egyptian sea in ancient days, and caused his people to go through on a highway in the midst of those mighty waters which stood like walls on each side of the assembly of Israel. So in the latter days he will not only cut off the tongue of the Egyptian sea, but the river in its seven streams will also be divided and men will go through dry-shod. This is the testimony of the prophets concerning the events that are to take place when the times of the Gentiles are fulfilled.

Journal of Discourses, Orson Pratt 18:4

How long will they who come from the north countries tarry in the heights of Zion? Some time. They have got to raise wheat, cultivate the grape, wine and oil, raise flocks and herds, and their souls will have to become as a watered garden. They will dwell in Zion a good while, and during that time, there will be twelve thousand chosen out of each of these ten tribes, besides twelve thousand that will be chosen from Judah, Joseph, and the remaining tribes, one hundred and forty-four thousand in all. Chosen for what? To be sealed in their foreheads. For what purpose? So that the power of death and pestilence and plague that will go forth in those days sweeping over the nations of the earth will have no power over them. These parties who are sealed in their foreheads will go forth among all people, nations and tongues, and gather up and hunt out the house of Israel, wherever they are scattered, and bring as many as they possibly can into the Church of the firstborn, preparatory to the great day of the coming of the Lord. One hundred and forty-four thousand missionaries! Quite a host. All this has got to take place. There are persons in this congregation who will be in the midst of Zion, when the ten tribes come to Zion from the north countries, and will assist in bestowing the blessings promised by the Almighty upon the heads of the tribes of Israel. There are servants of God in the midst of this congregation who will lay their hands upon many of each of these twelve thousand, chosen out of the ten tribes, and set them apart as missionaries to visit the nations of the earth and hunt up the remnants of the seed of Jacob. Having spoken concerning the gathering of the ten tribes, I will refer again to their Prophets. “Their Prophets shall hear his voice.” Do not think that we are the only people who will have Prophets. God is determined to raise up Prophets among that people, but he will not bestow upon them all the fulness of the blessings of the Priesthood. The fulness will be reserved to be given to them after they come to Zion. But Prophets will be among them while in the north, and a portion of the Priesthood will be there; and John the Revelator will be there, teaching, instructing and preparing them for this great work; for to him were given the keys for the gathering of Israel, at the time when he ate that little book while on the Isle of Patmos. At that time, John was a very old man; but the Lord told him that he must yet prophesy before many kingdoms, and nations, and peoples, and tongues, and he has got that mission to perform, and in the last days the spirit and power of Elias will attend his administrations among these ten tribes, and he will assist in preparing them to return to this land.

Journal of Discourses, Orson Pratt 18:7

[A]fter Zion is built in Jackson County, and after the Temple is built upon that spot of ground where the cornerstone was laid in 1831; after the glory of God in the form of a cloud by day shall rest upon that Temple, and by night the shining of a flaming fire will fill the whole heavens round about; after every dwelling place upon Mount Zion shall be clothed upon as with a pillar of fire by night, and a cloud by day, about that period of time, the ten tribes will be heard of, away in the north, a great company, as Jeremiah says, coming down from the northern regions, coming to sing in the height of the latter-day Zion. Their souls will be as a watered garden, and they will not sorrow any more at all, as they have been doing during the twenty-five hundred long years they have dwelt in the Arctic regions. They will come, and the Lord will be before their camp, he will utter his voice before that great army, and he will lead them forth as he led Israel in ancient days. This long chain of Rocky Mountains, that extends from the cold regions of the north away into South America, will feel the power of God, and will tremble before the hosts of Israel as they come to sing on the heights of Zion. In that day the trees of the field will clap like hands, says the Prophet, and in that day the Lord will open waters in the wilderness, and streams in the desert, to give drink to his chosen, his people Israel. And when they come to the height of Zion they shall be crowned with glory under the hands of the servants of God living in those days, the children of Ephraim, crowned with certain blessings that pertain to the Priesthood, that they could not receive in their own lands. In that day will be set apart twelve thousand out of each of these ten tribes–one hundred and twenty thousand persons ordained to the High Priesthood, after the order of the Son of God, to go forth to all people, nations, kindreds and tongues, for the salvation of the remnants of Israel in the four quarters of the earth, to bring as many as will come unto the Church of the Firstborn. Thus God will have twelve thousand out of all the tribes of Israel to fulfill his purposes; and when they have completed his work here on the earth, they will be called home to Zion, be crowned with glory and stand upon Mount Zion and sing the song of the redeemed, the song of the hundred and forty-four thousand, and the Father’s name will be written in their foreheads.

Journal of Discourses, Orson Pratt 18:7

After the times of the Gentiles are fulfilled… Then the word of the Lord will be–”O, ye, my servants, I have a new commission for you. Instead of going forth to convert the Gentile nations, go unto the remnants of the house of Israel that are scattered in the four quarters of the earth. Go and proclaim to them that the times of their dispersion are accomplished; that the times of the Gentiles are fulfilled; that the time has arrived for my people Israel, who have been scattered for generations in a dark and cloudy day, to gather unto their own homes again, and to build up old Jerusalem on its former heap. And then will commence the gathering of the Jews to old Jerusalem; then the ten tribes in the northern regions, wherever they may be, after having been concealed from the nations for twenty-five hundred years, will come forth and will return, as Jeremiah has said, from the north country.

Journal of Discourses, Orson Pratt 7:29

By-and-by, after you have fulfilled your missions to the nations of the Gentiles, and there will not any more of them repent–that is, when you have fully accomplished all that is required of you in relation to them, you will have another mission, and so will the Twelve, and that is to the house of Israel that may be among those nations; I mean the literal descendants of Jacob–the Jews, and the descendants of the other tribes that may be scattered among those nations. There are some from the ten tribes among them; but the body of the ten tribes are in the north country. You will find a few among all these Gentile nations: you will have to direct your attention to them after you have fulfilled your mission among the Gentiles, and their times are fulfilled. You will have something to do among the Jews, and then will be a time of great power, such as you and I have not dreamed of.

Journal of Discourses, Wilford Woodruff 4:44

Again, here are the ten tribes of Israel, we know nothing about them only what the Lord has said by His Prophets. There are Prophets among them, and by and by they will come along, and they will smite the rocks, and the mountains of ice will flow down at their presence, and a high way will be cast up before them, and they will come to Zion, receive their endowments, and be crowned under the hands of the children of Ephraim, and there are persons before me in this assembly today, who will assist to give them their endowments. They will receive their blessings and endowments, from under the children of Ephraim, who are the firstfruits of the kingdom of God in this dispensation, and the men will have to be ordained and receive their Priesthood and endowments in the land of Zion, according to the revelations of God.
