Helaman 11:20

And thus it did come to pass that

the people of Nephi began to prosper again in the land,

and began to build up their waste places,

and began to multiply and spread,

even until they did cover the whole face of the land,

both on the northward and on the southward,

from the sea west to the sea east.

Helaman 11:21

And it came to pass that the seventy and sixth year did end in peace.

And the seventy and seventh year began in peace;

and the church did spread throughout the face of all the land;

and the more part of the people,

both the Nephites and the Lamanites,

did belong to the church; and they did have exceedingly great peace in the land;

and thus ended the seventy and seventh year.

Helaman 11:22

And also they had peace in the seventy and eighth year,

save it were a few contentions concerning the points of doctrine

which had been laid down by the prophets.

Helaman 11:23

And in the seventy and ninth year there began to be much strife.

But it came to pass that Nephi and Lehi, and many of their brethren

who knew concerning the true points of doctrine,

having many revelations daily,

therefore they did preach unto the people,

insomuch that they did put an end to their strife in that same year.
