"Cause of their destruction"

1. Mosiah 8: 12
   12 And I say unto thee again: Knowest thou of any one that can translate? For I am desirous that these records should be translated into our language; for, perhaps, they will give us a knowledge of a remnant of the people who have been destroyed, from whence these records came; or, perhaps, they will give us a knowledge of this very people who have been destroyed; and I am desirous to know the cause of their destruction.
2. Alma 51: 16
   16 For it was his first care to put an end to such contentions and dissensions among the people; for behold, this had been hitherto a cause of all their destruction. And it came to pass that it was granted according to the voice of the people.
