“He [Enoch] Built a City That Was Called the City of Holiness, Even Zion”
19 And Enoch continued his preaching in righteousness unto the people of God. And it came to pass in his days, that he built a city that was called the City of Holiness, even Zion.
Elder D. Todd Christofferson said:
“Zion is both a place and a people. Zion was the name given to the ancient city of Enoch in the days before the Flood. ‘And it came to pass in his days, that he built a city that was called the City of Holiness, even Zion’ (Moses 7:19). This Zion endured for some 365 years (see Moses 7:68). The scriptural record states, ‘And Enoch and all his people walked with God, and he dwelt in the midst of Zion; and it came to pass that Zion was not, for God received it up into his own bosom; and from thence went forth the saying, Zion is fled’ (Moses 7:69). Later, Jerusalem and its temple were called Mount Zion, and the scriptures prophesy of a future New Jerusalem where Christ shall reign as ‘King of Zion,’ when ‘for the space of a thousand years the earth shall rest’ (Moses 7:53, 64).
“The Lord called Enoch’s people Zion ‘because they were of one heart and one mind, and dwelt in righteousness; and there was no poor among them’ (Moses 7:18). Elsewhere He said, ‘For this is Zion—the pure in heart’ (D&C 97:21).”
