Alma 27:21 - 27:25
Alma 27:21 And it came to pass that the chief judge sent a proclamation throughout all the land, desiring the voice of the people concerning the admitting their brethren, who were the people of Anti-Nephi-Lehi.
The chief judge sent a memo to the Nephites in the land of Zarahemla if they would want to take in the Anti-Nephi-Lehis and give them immunity status.
Alma 27:22 And it came to pass that the voice of the people came, saying: Behold, we will give up the land of Jershon, which is on the east by the sea, which joins the land Bountiful, which is on the south of the land Bountiful; and this land Jershon is the land which we will give unto our brethren for an inheritance.
The Nephites decide to give these folks the land of Jershon which is on the east side by the sea and which is just south of the land Bountiful.
This land is between the Lamanites that live in the wilderness on the east of the land of Zarahemla so they now become a buffer between the Lamanites and the Nephites on that side of the country. Not sure how much good it would do as these people were now pacifists.
Alma 27:23 And behold, we will set our armies between the land Jershon and the land Nephi, that we may protect our brethren in the land Jershon; and this we do for our brethren, on account of their fear to take up arms against their brethren lest they should commit sin; and this their great fear came because of their sore repentance which they had, on account of their many murders and their awful wickedness.
The Nephites further state that they will place an army between the Anti-Nephi-Lehis and the Lamanites in order to project them and help them keep their vow of not ever taking up arms again and maybe losing their souls. It was so hard for them to come this far and the Nephites just wanted them to not fall again.
Alma 27:24 And now behold, this will we do unto our brethren, that they may inherit the land Jershon; and we will guard them from their enemies with our armies, on condition that they will give us a portion of their substance to assist us that we may maintain our armies.
The Nephites were willing to do this if these folks will keep the army stationed there supplied with food and shelter.
Alma 27:25 Now, it came to pass that when Ammon had heard this, he returned to the people of Anti-Nephi-Lehi, and also Alma with him, into the wilderness, where they had pitched their tents, and made known unto them all these things. And Alma also related unto them his conversion, with Ammon and Aaron, and his brethren.
With this proposal, Ammon and Alma returned to the Anti-Nephi-Lehi’s camp and relayed this to the king. While there Alma told these folks of his conversion and that of the sons on Mosiah.
Don’t know if the king knew of the bad behavior of the boys prier to their coming on their mission, but he sure must have gotten a kick of hearing about them
