Mosiah 8
I didn’t realize that those people who found the plates of Ether also brought back swords and armor – I had thought they merely reported on what they found. I’ll bet that Limhi still expected that the Nephites from the land of Zerahemla were still alive considering that the writing on the plates was not in the Nephite language. I also believe that he wanted to know how the people of the record were destroyed not merely out of curiosity or spiritual awareness, but because he wanted to know if there was a factor (fierce animals, another people, disease) that he needed to be aware of for the safety of the Nephites.
