Isaiah 9:12 (King James Bible) for all this his anger is not turned away but his hand is stretched out still
As noted under 2 Nephi 13:14, the original Book of Mormon text frequently omitted the linking verb be that is italicized in the corresponding King James text. In this instance, the 1837 edition supplied the is before stretched, but the 1908 RLDS edition removed it since Joseph Smith did not mark its addition in the printer’s manuscript. For further discussion regarding the phrase “is stretched”, see 2 Nephi 19:17. The critical text will here maintain the earliest reading, which lacks the is.
Summary: Maintain in 2 Nephi 19:12 the reading of the printer’s manuscript; there the italicized is of the King James reading is lacking: “but his hand stretched out still”.
