According to McConkie, Millet, and Top, the establishment of Zion and the New Jerusalem will come "down out of heaven" (Ether 13:3) in both a literal and a symbolic way. In the symbolic way, the New Jerusalem will be built upon heavenly principles and under the influence of revelation to the Lord's chosen officers. . . . There is, however, an additional meaning--a very literal meaning--to this phrase. Enoch's city--the city of Holiness that was taken up into heaven (see Moses 7:13-21) will come down from heaven and be united with the earthly New Jerusalem (see Elder Bruce R. McConkie, Doctrinal New Testament Commentary 3:581; see also Millennial Messiah, pp. 302-9) [Joseph F. McConkie, Robert L. Millet, Brent L. Top, Doctrinal Commentary on the Book of Mormon, Vol. IV, p. 307]
