Regular repetition occurs when a phrase or expression occurs repeatedly in a passage. This technique is found in the Bible and can also be seen in the Book of Mormon.
On example is found in 1 Nephi 18:2
Now I, Nephi, did not work the timbers after the manner which was learned by men, neither did I build the ship after the manner of men; but I did build it after the manner which the Lord had shown unto me; wherefore, it was not after the manner of men.
Another is found in 2 Nephi 4:31–33:
O Lord, wilt thou redeem my soul? Wilt thou deliver me out of the hands of mine enemies? Wilt thou make me that I may shake at the appearance of sin? May the gates of hell be shut continually before me, because that my heart is broken and my spirit is contrite! O Lord, wilt thou not shut the gates of thy righteousness before me, that I may walk in the path of the low valley, that I may be strict in the plain road! O Lord, wilt thou encircle me around in the robe of thy righteousness! O Lord, wilt thou make a way for mine escape before mine enemies! Wilt thou make my path straight before me! Wilt thou not place a stumbling block in my way—but that thou wouldst clear my way before me, and hedge not up my way, but the ways of mine enemy.
Why does this not sound like what we would expect dictated from Joseph Smith? Wouldn’t he have likely avoided repeating himself like this? How would he know about this type of parallelism?
