Alma 43:22

Behold, now it came to pass, that they durst not come against the Nephites in the borders of Jershon; therefore they departed out of the land of Antionum, into the wilderness, and took their journey round about in the wilderness, away by the head of the river Sidon, that they might come into the land of Manti, and take possession of the land; for they did not suppose that the armies of Moroni would know whither they had gone.

They were afraid to attack the Nephites at the borders of Jershon. So they left the land of Antionum and went into the wilderness. They traveled around through the wilderness, near the start of the river Sidon. They wanted to come into the land of Manti and take over the land. They did not think Moroni’s armies would know where they had gone.

They didn’t dare attack the Nephites at Jershon. So they left Antionum and headed into the wilderness, circling around by the head of the Sidon River, planning to enter the land of Manti and take it. They thought Moroni’s armies wouldn’t know where they’d gone.
