“Now when I go up eagerly into the mount—or, to use a truer expression, when I both eagerly long and at the same time am afraid (the one through my hope and the other through my weakness), to enter within the cloud and hold converse with God, for so God commands: If any be an Aaron, let him go up with me, and let him stand near, being ready, if it must be so, to remain outside the cloud.”
