Doctrines and Covenants 84:31; “Therefore, as I said concerning the sons of Moses—for the sons of Moses and also the sons of Aaron shall offer an acceptable offering and sacrifice in the house of the Lord, which house shall be built unto the Lord in this generation, upon the consecrated spot as I have appointed—”
Titus 1:13-14; “This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith; 14 Not giving heed to Jewish fables, and commandments of men, that turn from the truth.”
The prophecy given by Smith in Kirtland, Ohio on September 22nd & 23rd, 1832 qualifies as a false prophecy. No temple was built in Missouri before Smith died in June 1844.
