The large congregation that assembled in the tabernacle on Sunday [October 21, 1877] was addressed by ELDER ORSON PRATT . . . He quoted from the book of Abraham, translated from Egyptian papyrus, to prove that the days mentioned in Genesis in connection with the creation were periods of one thousand years' duration, for they were reckoned by the time which prevailed on a planet called "Kolob" . . . Kolob was the celestial world whose time controlled this earth; this was before the spirits of men who inhabit this earth had all once dwelt, and there God sat and issued his commands for the government of the earth and others connected with it.
