Scattering and Gathering of Israel

1 Nephi 10:11–14

11 And it came to pass after my father had spoken these words he spake unto my brethren concerning the gospel which should be preached among the Jews, and also concerning the dwindling of the Jews in unbelief. And after they had slain the Messiah, who should come, and after he had been slain he should rise from the dead, and should make himself manifest, by the Holy Ghost, unto the Gentiles.
12 Yea, even my father spake much concerning the Gentiles, and also concerning the house of Israel, that they should be compared like unto an olive tree, whose branches should be broken off and should be scattered upon all the face of the earth.
13 Wherefore, he said it must needs be that we should be led with one accord into the land of promise, unto the fulfilling of the word of the Lord, that we should be scattered upon all the face of the earth.
14 And after the house of Israel should be scattered they should be gathered together again; or, in fine, after the Gentiles had received the fulness of the Gospel, the natural branches of the olive tree, or the remnants of the house of Israel, should be grafted in, or come to the knowledge of the true Messiah, their Lord and their Redeemer.

Elder Bruce R. McConkie wrote:

“Why was Israel scattered? The answer is clear; it is plain; of it there is no doubt. Our Israelite forebears were scattered because they rejected the gospel, defiled the priesthood, forsook the church, and departed from the kingdom. They were scattered because they turned from the Lord, worshipped false gods, and walked in all the ways of the heathen nations. . . . Israel was scattered for apostasy. The Lord in His wrath, because of their wickedness and rebellion, scattered them among the heathen in all the nations of the earth.

“What, then, is involved in the gathering of Israel? The gathering of Israel consists in believing and accepting and living in harmony with all that the Lord once offered His ancient chosen people. It consists of having faith in the Lord Jesus Christ, of repenting, of being baptized and receiving the gift of the Holy Ghost, and of keeping the commandments of God. It consists of believing the gospel, joining the Church, and coming into the kingdom. It consists of receiving the holy priesthood, being endowed in holy places with power from on high, and receiving all the blessings of Abraham, Isaac, and Jacob, through the ordinance of celestial marriage. And it may also consist of assembling to an appointed place or land of worship.

“Having this concept of the scattering and gathering of the chosen seed, we are able to understand the prophetic word relative thereto.”
