Mosiah 10:1 - 10:5
Mosiah 10:1 And it came to pass that we again began to establish the kingdom and we again began to possess the land in peace. And I caused that there should be weapons of war made of every kind, that thereby I might have weapons for my people against the time the Lamanites should come up again to war against my people.
Now, with the Lamanites intentions made know, the Nephites begin to arm the entire population to be prepared for other attaches. [I’m sure king Zeniff knew it would only be a manner of time before the Lamanites came against them again.]
Mosiah 10:2 And I set guards round about the land, that the Lamanites might not come upon us again unawares and destroy us; and thus I did guard my people and my flocks, and keep them from falling into the hands of our enemies.
To have some notice of future attaches, guards were set up around their territory. They also posted guards around their crops and herds. They were not going to be surprised again by the Lamanites.
Mosiah 10:3 And it came to pass that we did inherit the land of our fathers for many years, yea, for the space of twenty and two years.
Apparently this strategy worked and the Nephites were left along for the next 22 years.
Mosiah 10:4 And I did cause that the men should till the ground, and raise all manner of grain and all manner of fruit of every kind.
Everyone was busy in raising crops and fruit. [This is an agrarian society not engaged in manufacturing or merchandising. It would be interesting to know if there were people who specialized in say raising sheep and cattle and those who raised only grains. I’m not sure if people raised only what they consumed and there was no bartering for things that they needed that they did not raise. You can be sure it was not a age where information was the central needs of the people.]
Mosiah 10:5 And I did cause that the women should spin, and toil, and work, and work all manner of fine linen, yea, and cloth of every kind, that we might clothe our nakedness; and thus we did prosper in the land—thus we did have continual peace in the land for the space of twenty and two years.
Anyway everyone was busy with supporting themselves. The men raised crops of various kinds and the women attended to domestic duties. Through hard work and diligence to their responsibilities towards their families, the Nephites in the land of Nephi prospered for 22 years.
