16 And in the commencement of the sixty and seventh year the people began to grow exceedingly wicked again.
17 For behold, the Lord had blessed them so long with the riches of the world that they had not been stirred up to anger, to wars, nor to bloodshed; therefore they began to set their hearts upon their riches; yea, they began to seek to get gain that they might be lifted up one above another; therefore they began to commit secret murders, and to rob and to plunder, that they might get gain.
18 And now behold, those murderers and plunderers were a band who had been formed by Kishkumen and Gadianton. And now it had come to pass that there were many, even among the Nephites, of Gadianton's band. But behold, they were more numerous among the more wicked part of the Lamanites. And they were called Gadianton's robbers and murderers.
19 And it was they who did murder the chief judge Cezoram, and his son, while in the judgment–seat; and behold, they were not found.
20 And now it came to pass that when the Lamanites found that there were robbers among them they were exceedingly sorrowful; and they did use every means in their power to destroy them off the face of the earth.
21 But behold, Satan did stir up the hearts of the more part of the Nephites, insomuch that they did unite with those bands of robbers, and did enter into their covenants and their oaths, that they would protect and preserve one another in whatsoever difficult circumstances they should be placed, that they should not suffer for their murders, and their plunderings, and their stealings.*
