Isaiah 2:1 (King James Bible) Isaiah the son of Amoz
There has been a strong tendency in the text to misspell the name Amoz (the father of Isaiah) as the name Amos (the biblical prophet). Here in 2 Nephi 12:1, Oliver Cowdery first wrote the name as Amos in the printer’s manuscript but then corrected it (after several tries) to Amoz. The 1841 British edition introduced the incorrect spelling Amos, which persisted in the LDS text in all editions up through the early printings of the 1981 edition, finally being corrected to Amoz in 1983. The very same variation is found later on near the end of Nephi’s long quotation from Isaiah:
In this instance, the original manuscript is extant and has the correct spelling Amoz. 𝓞 is not extant for 2 Nephi 12:1 but probably also read correctly as Amoz.
Summary: Maintain the spelling Amoz in 2 Nephi 12:1 and 2 Nephi 23:1.
