3 nephi 7

9 Now this secret combination, which had brought so great iniquity upon the people, did gather themselves together, and did place at their head a man whom they did call Jacob;

10 And they did call him their king; therefore he became a king over this wicked band; and he was one of the chiefest who had given his voice against the prophets who testified of Jesus.

11 And it came to pass that they were not so strong in number as the tribes of the people, who were united together save it were their leaders did establish their laws, every one according to his tribe; nevertheless they were enemies; notwithstanding they were not a righteous people, yet they were united in the hatred of those who had entered into a covenant to ^adestroy the government.
