Isaiah 50:1 (King James Bible) behold for your iniquities have ye sold yourselves
The original manuscript is extant here and has ye for the subject pronoun, in agreement with the King James Bible. While copying from 𝓞 into 𝓟, Oliver Cowdery initially wrote you but later corrected it to ye, probably when he proofed 𝓟 against 𝓞 (the level of ink flow is somewhat heavier and the quill appears to be sharper). In the original text of the Book of Mormon, there are examples of both ye and you as the subject pronoun. The tendency has been to replace the archaic ye with the modern-day you. This kind of change has occurred quite a few times in the history of the text. For a complete listing, see ye in volume 3. In the critical text, we will let the earliest textual sources determine in each case whether the reading should be ye or you.
Summary: Maintain the subject pronoun ye here in 2 Nephi 7:1, the reading of the original manuscript.
