Helaman 2:5

therefore he did flatter them, and also Kishkumen, that if they would place him in the judgement seat, he would grant unto those which belonged to his band that they should be placed in power and authority among the people; therefore Kishkumen sought to destroy Helaman.

He made big promises to them and to Kishkumen. He said if they would make him judge, he would give his group members power and high positions among the people. So Kishkumen tried to kill Helaman.

Gadianton made promises to Kishkumen and the others: if they’d get him into the judge’s seat, he’d give them positions of power and authority. So Kishkumen set out to kill Helaman.
