Welch argues that extended inverted parallel structures in the Book of Mormon resemble ancient Hebrew literary forms and help explain the organization and meaning of passages. In his 1969 study, he argues that Joseph Smith was unlikely to have learned or independently created these complex patterns, making them evidence for an ancient literary setting.
Welch reconstructs the 1829 translation calendar and estimates roughly sixty available working days after accounting for other activities and interruptions. He treats the speed and continuity of dictation as significant features of the production record, while this study does not select a specific mechanism for supplying the English words.
