2 Nephi 6
It is interesting to note that this is Nephi recording these words, not because Jacob spoke them, and not because Jacob thought them worthy to be in the sacred record, but because Nephi felt they were an appropriate addition to the book. Perhaps that is because Nephi had recommended to Jacob that the people needed to hear more about Isaiah. According to this there are Jews who still honestly wait for their Savior and they shall be saved at His coming. There are also Jews who accept their heritage and culture, but do not believe in any Savior and they shall not be saved at His coming except possibly physically saved.
