10 And he also placed armies on the south, in the borders of their possessions, and caused them to erect fortifications that they might secure their armies and their people from the hands of their enemies.
11 And thus he cut off all the strongholds of the Lamanites, in the east wilderness: yea, and also on the west, fortifying the line between the Nephites and the Lamanites, between the land of Zarahemla and the land of Nephi; from the west sea, running by the head of the river Sidon;
12 The Nephites possessing all the land northward; yea, even all the land which was northward of the land Bountiful, according to their pleasure.
13 Thus Moroni, with his armies, which did increase daily, because of the assurance of protection which his works did bring forth unto them; therefore they did seek to cut off the strength and the power of the Lamanites, from off the lands of their possessions, that they should have no power upon the lands of their possessions.
14 And it came to pass that the Nephites began the foundation of a city; and they called the name of the city Moroni; and it was by the east sea; and it was on the south by the line of the possessions of the Lamanites.
15 And they also began a foundation for a city between the city of Moroni and the city of Aaron, joining the borders of Aaron and Moroni; and they called the name of the city, or the land, Nephihah.
16 And they also began, in that same year, to build many cities on the north; one in a particular manner which they called Lehi, which was in the north, by the borders of the sea-shore. And thus ended the twentieth year.
17 And in these prosperous circumstances were the people of Nephi, in the commencement of the twenty and first year of the reign of the Judges over the people of Nephi.
18 And they did prosper exceedingly, and they became exceeding rich; yea, and they did multiply, and wax strong in the land.
19 And thus we see how merciful and just are all the dealings of the Lord, to the fulfilling of all his words unto the children of men;
20 Yea, we can behold that his words are verified, even at this time, which he spake unto Lehi saying, Blessed art thou and thy children; and they shall be blessed; inasmuch as they shall keep my commandments, they shall prosper in the land.
