Punctuation is important.  The Book of Mormon uses dashes/hyphens quite a bit and the choice of an em dash versus an en dash makes a significant difference in how a particular passage may be read, pronounced and understood.

One particular construction in 1 Nephi Chapter 14:3 effectively demonstrates the difference and we should be careful how we read this verse out loud in the home or at church.

1 Nephi 14:3
And that great pit, which hath been digged for them by that great and abominable church, which was founded by the devil and his children, that he might lead away the souls of men down to hell—yea, that great pit which hath been digged for the destruction of men shall be filled by those who digged it, unto their utter destruction, saith the Lamb of God; not the destruction of the soul, save it be the casting of it into that hell which hath no end.
