Here is another case of Joseph Smith’s stylistic editing for the 1837 edition. In this instance, he removed the repetitiveness of “and I beheld”, although elsewhere such repetition involving beheld has been retained:
One could remove the repetitive “yea and I beheld” here as well, but of course such stylistic editing is unnecessary. Similarly, the original text in 1 Nephi 13:38 reads perfectly well.
Summary: Restore the original use of the repetitive “and I beheld” in 1 Nephi 13:38; this is one more example of Joseph Smith’s stylistic editing in the first part of the text.
