Here Joseph Smith removed the awkward syntax of “we will not that he shall be our ruler” by replacing the that-clause with an infinitive clause. Yet elsewhere he left two parallel examples unchanged:
The parallelism between 1 Nephi 18:10 and 2 Nephi 5:3 is very striking:
we will not that our younger brother shall be a ruler over us we will not that he shall be our ruler
Joseph’s editing in 2 Nephi 5:3 was stylistically motivated and was never consistently applied. (For a related kind of stylistic editing, see 2 Nephi 5:15, 17.)
Summary: Restore the original that-clause in 2 Nephi 5:3 (“we will not that he shall be our ruler”).
