Many were brought

1. Alma 17: 4
     4 And they had been teaching the word of God *for the space of fourteen years among the Lamanites, having had much success in bringing many to the knowledge of the truth; yea, by the power of their words many were brought before the altar of God, to call on his name and confess their sins before him.
2. Alma 23: 6
     6 And as sure as the Lord liveth, so sure as many as believed, or as many as were brought to the knowledge of the truth, through the preaching of Ammon and his brethren, according to the spirit of revelation and of prophecy, and the power of God working miracles in them—yea, I say unto you, as the Lord liveth, as many of the Lamanites as believed in their preaching, and were converted unto the Lord, never did fall away.
3. Alma 35: 14
     14 And Alma, and Ammon, and their brethren, and also the two sons of Alma returned to the land of Zarahemla, after having been instruments in the hands of God of bringing many of the Zoramites to repentance; and as many as were brought to repentance were driven out of their land; but they have lands for their inheritance in the land of Jershon, and they have taken up arms to defend themselves, and their wives, and children, and their lands.
