The Bible
Helaman 4
Nephite dissenters and the Lamanites join forces and take the land of Zarahemla—The Nephites’ defeats come because of their wickedness—The Church dwindles, and the people become weak like the Lamanites. About 38–30 B.C.
6And the Nephites and the armies of Moronihah were driven even into the land of Bountiful;
17And thus ended the sixty and first year of the reign of the judges.
