Alma 22:26 - 22:30
Alma 22:26 And it came to pass that when the king saw that the people were pacified, he caused that Aaron and his brethren should stand forth in the midst of the multitude, and that they should preach the word unto them.
When the king saw that the people were comfortable with the king’s explanation of what had happened to him, he asked Aaron and his companions to speak to the people.
Alma 22:27 And it came to pass that the king sent a proclamation throughout all the land, amongst all his people who were in all his land, who were in all the regions round about, which was bordering even to the sea, on the east and on the west, and which was divided from the land of Zarahemla by a narrow strip of wilderness, which ran from the sea east even to the sea west, and round about on the borders of the seashore, and the borders of the wilderness which was on the north by the land of Zarahemla, through the borders of Manti, by the head of the river Sidon, running from the east towards the west—and thus were the Lamanites and the Nephites divided.
The king then sent a memo to all the people under his control which stretched from sea to sea and up to the wilderness which formed a natural barrier between the Nephites and the Lamanites.
Alma 22:28 Now, the more idle part of the Lamanites lived in the wilderness, and dwelt in tents; and they were spread through the wilderness on the west, in the land of Nephi; yea, and also on the west of the land of Zarahemla, in the borders by the seashore, and on the west in the land of Nephi, in the place of their fathers’ first inheritance, and thus bordering along by the seashore.
In the wilderness live the more nomadic Lamanites who live in tents as differentiated from those who live in permanent settlements.
Alma 22:29 And also there were many Lamanites on the east by the seashore, whither the Nephites had driven them. And thus the Nephites were nearly surrounded by the Lamanites; nevertheless the Nephites had taken possession of all the northern parts of the land bordering on the wilderness, at the head of the river Sidon, from the east to the west, round about on the wilderness side; on the north, even until they came to the land which they called Bountiful.
Since the Lamanites also live in other areas of the land, the Nephite found themselves in Zarahemla and Bountiful surrounded by Lamanite peoples.
Alma 22:30 And it bordered upon the land which they called Desolation, it being so far northward that it came into the land which had been peopled and been destroyed, of whose bones we have spoken, which was discovered by the people of Zarahemla, it being the place of their first landing.
The Nephite lands also bordered on the land they called Desolation to the north which contain evidence of a past civilization that had been destroyed and had only dwelt in that one area.
