Textual: The awkwardness that frequently comes from the modern chapter divisions is highlighted in this verse. As the beginning of a new chapter we can lose the context that explains the actions. In this verse we have judges who are Gadiantons becoming angry. The reason for their anger is in the previous chapter. In Helaman 7:25 Nephi has squarely laid blame at the feet of the Gadiantons and predicted them as the cause of the coming downfall of the Nephites. Of course the Gadianton judges would take offense. This section belongs with, and should be read as part of, the events in chapter 7.
The audacity of Nephi’s statement can be more clearly understood if we remember that these Gadiantons are judges, and that they are judges because their political party is in control, and in the majority. Nephi is speaking directly against the ruling government, and the majority opinion of the people. Of what crime are the judges accusing Nephi? Treason. Nephi is fomenting rebellion against the rulers placed in power by the voice of the people.
