1 Kings 1:27-29

27 And it came to pass that the ninety and third year did also pass away in peace, save it were for the Gadianton robbers, who dwelt upon the mountains, who did infest the land; for so strong were their holds and their secret places that the people could not overpower them; therefore they did commit many murders, and did do much slaughter among the people.

28 And it came to pass that in the ninety and fourth year they began to increase in a great degree, because there were many dissenters of the Nephites who did flee unto them, which did cause much sorrow unto those Nephites who did remain in the land.

29 And there was also a cause of much sorrow among the Lamanites; for behold, they had many children who did grow up and began to wax strong in years, that they became for themselves, and were led away by some who were Zoramites, by their lyings and their flattering words, to join those Gadianton robbers.
