1 Now it came to pass that after the sons of Mosiah had done all these things, they took a small number with them and returned to their father, the king, and desired of him that he would grant unto them that they might, with these whom they had selected, go up to the land of Nephi that they might preach the things which they had heard, and that they might impart the word of God to their brethren, the Lamanites— [There was a small group of men, which included the sons of Mosiah.]
2 That perhaps they might bring them to the knowledge of the Lord their God, and convince them of the iniquity of their fathers; and that perhaps they might cure them of their hatred towards the Nephites, that they might also be brought to rejoice in the Lord their God, that they might become friendly to one another, and that there should be no more contentions in all the land which the Lord their God had given them. [A persistent desire among the Nephites was to have peace with the Lamanites. They saw more in common than what was different.]
3 Now they were desirous that salvation should be declared to every creature, for they could not bear that any human soul should perish; yea, even the very thoughts that any soul should endure endless torment did cause them to quake and tremble. [They were filled with the love of God (charity), which magnifies the desire to preach, and save souls.]
4 And thus did the Spirit of the Lord work upon them, for they were the very vilest of sinners. And the Lord saw fit in his infinite mercy to spare them; nevertheless they suffered much anguish of soul because of their iniquities, suffering much and fearing that they should be cast off forever.
A common struggle for those who were horrible sinners who have repented and come to Christ is that they doubt themselves, often thinking they are unworthy because of past sins. We may never forget what we have done to offend the Lord, but in their case it brought heavy sorrow.
Some of the greatest missionaries in the history of the world suffered from horrible guilt. The Apostle Paul was one such man, and relished his suffering as a manner of recompense and evidence to the Lord that He truly loved Him above all things, even though the Lord never required it. Satan would have the repentant sinner think they are not worthy, but the true servant uses such guilt as a motivator to show the Lord their love and declare “How great is thy mercy!”
5 And it came to pass that they did plead with their father many days that they might go up to the land of Nephi.
6 And king Mosiah went and inquired of the Lord if he should let his sons go up among the Lamanites to preach the word. [He only prayed for his sons. This would be a hard sacrifice for King Mosiah who had great trepidations against such an act. In his heart he did not want them to go, but was humble and meek in his prayers to know the Lord’s will.]
7 And the Lord said unto Mosiah: Let them go up, for many shall believe on their words, and they shall have eternal life; and I will deliver thy sons out of the hands of the Lamanites. [It takes much faith sometimes to receive such a risky revelation. Mosiah’s wife had to also receive her own comfort from the Lord.]
8 And it came to pass that Mosiah granted that they might go and do according to their request.
9 And they took their journey into the wilderness to go up to preach the word among the Lamanites; and I shall give an accountof their proceedings hereafter. [A good place to stop and continue the record of the people of Nephi in the land of Zarahemla.]
There is much backstories and subplots in the Book of Mormon that seamlessly intertwine to help one to see the Lord’s hand in preparing this people for greater things.
10 Now king Mosiah had no one to confer the kingdom upon, for there was not any of his sons who would accept of the kingdom. [Had they not been converted to the Lord the outcome of the kingdom would have been far different.]
11 Therefore he took the records which were engraven on the plates of brass, and also the plates of Nephi, and all the things which he had kept and preserved according to the commandments of God, after having translated and caused to be written the records which were on the plates of gold which had been found by the people of Limhi, which were delivered to him by the hand of Limhi;
12 And this he did because of the great anxiety of his people; for they were desirous beyond measure to know concerning those people who had been destroyed.
13 And now he translated them by the means of those two stones [The Urim and Thummim, which had been passed down since the time of the Brother of Jared. These two stones were two of the original stones used to light the barges when the Jaredites came across the waters.] which were fastened into the two rims of a bow.
14 Now these things were prepared from the beginning [Prepared from when the people first inherited this land after the flood], and were handed down from generation to generation, for the purpose of interpreting languages; [These constitute seer stones.

15 And they have been kept and preserved by the hand of the Lord, that he should discover to every creature who should possess the land the iniquities and abominations of his people;
16 And whosoever has these things is called seer, after the manner of old times. [A Seer is one who sees the past, present, and future, according to the Lord’s will. A Revelator is one who reveals what has not been revealed before. A prophet is one who reveals the Lord’s word to the people. One can be a Prophet and not be a Revelator or a Seer.]
17 Now after Mosiah had finished translating these records, behold, it gave an account of the people who were destroyed, from the time that they were destroyed back to the building of the great tower, at the time the Lord confounded the language of the people and they were scattered abroad upon the face of all the earth, yea, and even from that time back until the creation of Adam. [The record of the sealed portion of the Book of Mormon contains the history of the Jaredites, the visions of the Brother of Jared, and unknown history concerning the people all the way back to Adam. In this record will be information regarding the City of Salem and its ascension, why the people of Jared were not included in this group. The record contains information regarding the pre-deluvian times that led up to the flood. There is much regarding the secret combinations, and this record stands as a witness against the evil that has ravished our world. There is also much information regarding the Everlasting Covenant as it was revealed to the Brother of Jared, and for this purpose, and a few others, the Lord will withhold its contents from us until Zion is established.]
18 Now this account did cause the people of Mosiah to mourn exceedingly, yea, they were filled with sorrow; nevertheless it gave them much knowledge, in the which they did rejoice.
19 And this account shall be written hereafter; for behold, it is expedient that all people should know the things which are written in this account. [And then the prophecy shall be fulfilled that then all things shall be revealed, and people shall read them upon the housetops. 2 Nephi 27:11]
20 And now, as I said unto you, that after king Mosiah had done these things, he took the plates of brass, and all the things which he had kept, and conferred them upon Alma, who was the son of Alma; yea, all the records, and also the interpreters, and conferred them upon him, and commanded him that he should keep and preserve them, and also keep a record of the people, handing them down from one generation to another, even as they had been handed down from the time that Lehi left Jerusalem. [Now the records are passed from the line of Kings to the holy men of God.]
