President Brigham Young said he would give the mind and will of the Lord concerning the Latter-day Saints in their temporal life, which was that they should manufacture their own clothing, just as fast as they possibly can. ... he said they [the Jews] never will believe until Jesus comes again, and preaching will have no more effect upon them than it will upon the color of the descendants of Cain. When all the rest of Adam's posterity shall be redeemed, then, and not till then will the children of Cain receive the promised blessing of restoration.
