Joseph Fielding Smith
The Lord has promised that these scattered members of the house of Israel shall in the last days be gathered. They shall come back from their long dispersion to inherit the lands of the covenant in the due time of the Lord and no mortal hand or power can stop them. . . . One of the most interesting and significant parables ever written is that revealed to Zenos and recorded in the fifth chapter of Jacob in the Book of Mormon. It is a parable of the scattering of Israel. If we had the full key to the interpretation, then we would have in detail how Israel was transplanted in all parts of the earth. Thus through this scattering the Lord has caused Israel to mix with the nations and bring the Gentiles within the blessings of the seed of Abraham. We are preaching the gospel now in all parts of the world, and for what purpose? To gather out from the Gentile nations the lost sheep of the house of Israel. It is by this scattering that the Gentile nations have been blessed, and if they will truly repent they are entitled to all the blessings promised to Israel, “which are the blessings of salvation, even of life eternal.” 1
“We are called of God. We have been gathered from the distant nations, and our lives have been hid with Christ in God, but we have not known it. The Lord has been watching over us from the hour of our birth. We are of the seed of Ephraim, and of Abraham, and of Joseph, who was sold into Egypt, and these are the instruments that God has kept in the spirit world to come forth in these latter days to take hold of this kingdom and build it up.”2

“Of this glorious day of restorations and gathering, another Nephite prophet said ‘The Lord . . . has covenanted with all the house of Israel,’ that ‘the time comes that they shall be restored to the true Church and fold of God’; and that ‘they shall be gathered home to the lands of their inheritance, and shall be established in all their lands of promise.’ (2 Ne. 9:1-2)
Now I call your attention to the facts, set forth in these scriptures, that the gathering of Israel consists of joining the true church; of coming to a knowledge of the true God and of his saving truths; and of worshiping him in the congregations of the Saints in all nation and among all peoples. Please note that these revealed words speak of the folds of the Lord; of Israel being gathered to the lands of their inheritance, Of Israel being established in all their lands of promise; and of there being congregations of the covenant people of the Lord in every nation, speaking every tongue, and among every people when the Lord comes again.” 3
Ezekiel 20:34, 41
And I will bring you out from the people, and will gather you out of the countries wherein ye are scattered, with a mighty hand, and with a stretched out arm, and with fury poured out.
I will accept you with your sweet savour, when I bring you out from the people, and gather you out of the countries wherein ye have been scattered; and I will be sanctified in you before the heathen.
For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out.
As a shepherd seeketh out his flock in the day that he is among his sheep that are scattered; so will I seek out my sheep, and will deliver them out of all places where they have been scattered in the cloudy and dark day.
And I will bring them out from the people, and gather them from the countries, and will bring them to their own land, and feed them upon the mountains of Israel by the rivers, and in all the inhabited places of the country.
1 Nephi 19:16
Yea, then will he remember the isles of the sea; yea, and all the people who are of the house of Israel, will I gather in, saith the Lord, according to the words of the prophet Zenos, from the four quarters of the earth.
3 Nephi 20:13
And then shall the remnants, which shall be scattered abroad upon the face of the earth, be gathered in from the east and from the west, and from the south and from the north; and they shall be brought to the knowledge of the Lord their God, who hath redeemed them.
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;
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.
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.
For mine eyes are upon all their ways: they are not hid from my face, neither is their iniquity hid from mine eyes.
Jeremiah 23:3, 7, 8
And I will gather the remnant of my flock out of all countries whither I have driven them, and will bring them again to their folds; and they shall be fruitful and increase.
Therefore, behold, the days come, saith the Lord, that they shall no more say, The Lord liveth, which brought up the children of Israel out of the land of Egypt;
But, The Lord liveth, which brought up and which led the seed of the house of Israel out of the north country, and from all countries whither I had driven them; and they shall dwell in their own land.
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,
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;
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.
“Now the same spirit of revelation that sought out the Prophet Joseph [Smith] from the loins of Joseph that was sold into Egypt…has also called the children of Abraham from among the kingdoms and countries of the earth to first hear and then embrace the everlasting Gospel; and the remnants of the seed of Ephraim who were scattered from Palestine and who colonized the shores of the Caspian Sea and thence made their way into the north of Europe, western Scandinavia and northern Germany, penetrating Scotland and England, and conquering those nations and reigning as monarchs of Great Britain, and mingling their seed with the Anglo Saxon race, and spreading over the waters a fruitful vine, as predicted by Jacob, whose branches should run over the wall. Their blood has permeated European society, and it coursed in the veins of the early colonists of America. And when the books shall be opened and the lineage of all men known, it will be found that they have been first and foremost in everything noble among men in the various nations in breaking off the shackles of kingcraft and priestcraft and oppression of every kind, and the foremost among men in upholding and maintaining the principles of liberty and freedom upon this continent and establishing representative government, and thus preparing the way for the coming forth of the fullness of the Gospel. And it is the foremost of those spirits whom the Lord has prepared to receive the Gospel when it was presented to them, and who did not wait for the Elders to hunt them from the hills and corners of the earth, but they were hunting for the Elders, impelled by a spirit which then they could not understand; and for this reason were they among the first Elders of the Church; they and the fathers having been watched over from the days that God promised those blessings upon Isaac and Jacob and Joseph and Ephraim.”

“…all Israel, the Lamanites and the Ten Tribes included, shall be gathered if and when they believe the Book of Mormon. The Ten Tribes shall return after they accept the Book of Mormon; then they shall come to Ephraim to receive their blessings, the blessings of the house of the Lord, the blessings that make them heirs of the covenant God made with their father Abraham. 
“Moses, who mediated the cause of his erring brethren in ancient times, and to whom the Lord revealed the doctrine of the scattering and the doctrine of the gathering, is the very one who came in resurrected glory to give the needed authorization and keys to Joseph Smith and Oliver Cowdery. As the holy word attests: “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.” (D&C 110:11.)
Two things are involved in this commission. First Israel — all Israel, the Ten Tribes included — is to be gathered “from the four parts of the earth,” out of every nation and from among every people. They are to be gathered into the true church and fold of the God of Israel. This gathering is primarily spiritual, but it is also temporal in that the gathered sheep are assembled into the stakes of Zion where the living waters flow. But, next, this commission directs the one who holds the keys of the gathering, meaning the President of the Church, to lead the Ten Tribes from the land of the north to their destined Palestinian homeland. They will be led to their promised inheritances after they join the Church, after they return unto the Lord, after they believe in Christ and accept his gospel, after they receive, individually and collectively, the Abrahamic covenant again.”
