Isaiah 4:6 (King James Bible) and for a place of refuge and for a covert from storm and from rain
Here the Book of Mormon text does not repeat the preposition for. Although it is possible that the repeated for was accidentally deleted in the early transmission of the text, two other passages in this long Isaiah quotation (2 Nephi 12–24) show that the Book of Mormon text sometimes omits the repeated preposition for:
Summary: Maintain the lack of the repeated preposition for in 2 Nephi 14:6 as well as in 2 Nephi 17:25 and 2 Nephi 18:14.
