“ And they were taught to hate the children of God, even as the Lamanites were taught to hate the children of Nephi from the beginning.
40 And it came to pass that two hundred and forty and four years had passed away, and thus were the affairs of the people. And the more wicked part of the people did wax strong, and became exceedingly more numerous than were the people of God. ”

“ And as many as did come unto them, and did truly repent of their sins, were baptized in the name of Jesus; and they did also receive the Holy Ghost.
2 And it came to pass in the thirty and sixth year, the people were all converted unto the Lord, upon all the face of the land, both Nephites and Lamanites, and there were no contentions and disputations among them, and every man did deal justly one with another. ”
