Helaman 4:5

And in the fifty and seventh year, they did come down against the Nephites to battle, and they did commence the work of death; yea, insomuch, that in the fifty and eighth year of the reign of the Judges, they succeeded in obtaining possession of the land of Zarahemla; yea, and also all the lands, even unto the land which was near the land Bountiful;

In the fifty-seventh year, they came down to fight the Nephites. They started the work of death. In the fifty-eighth year of the judges’ rule, they took over Zarahemla. They also took all the lands up to the land near Bountiful.

In the fifty-seventh year, they came down to fight the Nephites and began their campaign of death. By the fifty-eighth year, they’d captured the land of Zarahemla and all the territories right up to Bountiful.
