Hamblin and Merrill: "The Book of Mormon mentions the sword 156 times"
William J. Hamblin, A. Brent Merrill,
The Book of Mormon mentions the sword 156 times, more than any other weapon. For the sake of discussion, we have divided its usage into two categories: literary or metaphorical and military-technical. We have classified seventy-eight instances as metaphorical and seventy-eight as technical (though many occurrences are ambiguous and could fall in either category). There are four major types of sword metaphors used in the Book of Mormon: fighting or warfare in general, violent death, military vigilance, and divine power. The book metaphorically describes fighting in battle with eighteen different sword phrases, violent death with seven major metaphors, military preparedness with two phrases, and divine power with five metaphors. —(Click here to continue)
