Metcalfe on the shift of his use of the phrase therefore and wherefore for Joseph Smith

Mosian priority


“Enveloping is particularly evident in discussion of the advent of Jesus. For example, early in the narrative Nephi relates that Lehi (1 Ne. 10:4), an angel (19:8), and “the prophets” (2 Ne. 25:19) had all predicted that Jesus would be born 600 years from the time Lehi left Jerusalem. However, subsequent Book of Mormon prophets seem unaware of these extraordinary oracles.
At a Nephite revival, King Benjamin comments that “the time cometh, and is not far distant … [that the Lord] shall come down from heaven … and shall dwell in a tabernacle of clay” (Mosiah 3:5). This comment is surprising since the scriptures he possessed presumably told him this would not occur for over 120 years. Alma speaks of Jesus’ advent in similarly general terms: “the kingdom of heaven is soon at hand” (Alma 5:28, 50); “the time is not far distant” (7:7); “not many days hence” (9:26); and “the day of salvation draweth nigh” (13:21).25 Alma sincerely hopes “that it might be in [his] day” (v. 25). His reticence or inability to disclose Jesus’s birth date is explicable in his admission, “we know not how soon” (ibid.; emphasis added). Thus Alma, Benjamin, and their audiences did not know what Lehi, Nephi, an angel, anonymous Old World prophets, and their sacred literature had known with certainty: that Jesus would be born 600 years after the Lehites departed for the Americas.
When Samuel the Lamanite subsequently enters the scene, in contrast to Benjamin’s and Alma’s imprecision, he boldly specifies “for five years more cometh … then cometh the Son of God” (Hel. 14:2). Absent is any indication that Samuel merely echoes the inspired utterances of his forebears, Lehi and Nephi, or other prophets, including an angel. This particular point is paramount, for the potency of Samuel’s oracle lies in its absolute uniqueness. If Samuel’s prophecy is simply a repetition of earlier prophecies, it could scarcely be used to authenticate his prophetic calling (16:4-5). When Samuel’s followers are sentenced to death prior to Jesus’s advent, it is because his prophecy did not appear to be true, excluding any mention of Lehi or Nephi (3 Ne. 1:5).
The enveloping is obvious: Lehi and Nephi explicitly preach the date of Jesus’s birth; Benjamin and Alma speak only in generalities; [p.417] Samuel, like Nephi, is explicit. But when we analyze the passages in the order they were dictated, the enveloping pattern is replaced with a linear pattern. Prophets in the earliest part of the dictation lack specific knowledge of Jesus’ birth date. However, with Samuel a date of five years is given. At the expiration of the allotted time, the signs appear as prophesied. In this context the narrative explains: (1) that “father Lehi … Nephi … almost all of our fathers … have testified of the coming of Christ” (Hel. 8:22); and (2) that the year Jesus was born “was six hundred years from the time that Lehi left Jerusalem” (3 Ne. 1:1).
Passages such as these paved the way for the next stage of thematic development. What started as an editorial remark that 600 years had elapsed is transformed into a literal prophecy from the lips of Lehi, Nephi, an angel, and unidentified prophets. These prophecies were not dictated until the 600-year date had been firmly established in 3 Nephi.26”

how Joseph Smith was implementing ideas into the Book of Mormon’s early authors that were not developed until later in the book.
