4:19 And this he did that he himself might go forth among his people, or among the people of Nephi, that he might preach the word of God unto them, to stir them up in remembrance of their duty, and that he might pull down, by the word of God, all the pride and craftiness and all the contentions which were among his people, seeing no way that he might reclaim them save it were in bearing down in pure testimony against them.

 4:20 And thus in the commencement of the ninth year of the reign of the judges over the people of Nephi, Alma delivered up the judgment-seat to Nephihah, and confined himself wholly to the high priesthood of the holy order of God, to the testimony of the word, according to the spirit of revelation and prophecy.

 5:1 Now it came to pass that Alma began to deliver the word of God unto the people, first in the land of Zarahemla, and from thence throughout all the land.
