According to Victor Ludlow, there are changes found in 2 Nephi 6:17, as quoted by Jacob. Interestingly, the same passage as quoted by Nephi in 1 Nephi 21:25 does not have these changes, but is basically the same as the King James Version. It appears that Jacob changed the order of some phrases by dropping the last phrase of verse 25, "I will save thy children" (KJV) and adding the phrase "For the Mighty God shall deliver his covenant children," which conveys the same message found earlier in the verse. The only major difference is his substitution of "covenant people" for "children," defining God's children as those who keep his covenants. [Victor L. Ludlow, Isaiah: Prophet, Seer, and Poet, p. 418]
