“One can hardly read the ages attributed to the ancient patriarchs without a sense of wonder. Methuselah, we are told, lived nine hundred and sixty-nine years (Moses 8:7), Adam, nine hundred and thirty years (Moses 6:12), Noah lived to be nine hundred and fifty years (Genesis 9:29), and so on. The question is frequently asked whether the ancient year was of the same length as in our modern calendar. Lehi seemed to affirm such to be the case. Their days were ‘prolonged’ and ‘their time was lengthened,’ by the command of God, we are told” (McConkie and Millet, Doctrinal Commentary, 1:198–99).
