Dear 100 Hour Board,
I think you misunderstood the "fair as the moon"/"fair as the sun" question. See Song of Solomon 6:10, D&C 5:14, D&C 105:31, and D&C 109:73; then you might be better able to contribute your two cents. Somebody Important likes that phrase enough to have used it a few times, and He also likes interchanging the adjectives, for some reason (or perhaps no reason at all).
(By the way, I had some friends as a freshman who decided to put phrases from the Song of Solomon on flash cards and practiced using them as pickup lines. "As a piece of a pomegranate are thy temples within thy locks." Crazy freshmen.)
