I Nephi 22:25-26
25.  And he gathereth his sheep, and they know him; and there shall be one fold and one Shepherd; and he shall feed his sheep, and in him they shall find pasture.
26.  And because of the righteousness of his people, Satan hath no power; wherefore, he cannot be loosed for the space of many years; for he hath no power over the hearts of the people, for they dwell in righteousness, and the Holy One of Israel reigneth.
