Helaman 11

Helaman 11:36

"And in the eighty and second year they began again to forget the Lord their God. And in the eighty and third year they began to wax strong in iniquity. And in the eighty and forth year they did not mend their ways."

The people were growing more and more wicked. As they continually did not repent they became more lost and farther from the Spirit. When repentance is delayed it is so much harder to change.
