In a letter dated February 18, 1861, to Brigham Young, W. W. Phelps offered a translation of Zech 2:6-9 (Heb: 2:10-13) based on Johannes Michaelis' translation of the pericope. Phelps interprets this pericope in light of the then-future Civil War which would begin on April 1861 (cf. D&C 87), concluding that
By
1866, these "slaves" will have a holiday as wonderful as their
masters . . . sic transit gloria mundi [Thus passes
the glory of the world]
Interestingly, this would actually be fulfilled with the establishment of a U.S. holiday on June 19, 1866.
