LX. (172) There is a certain peculiarity which is attached to this word. For when it calls the soul to itself, it excites a congealing power in everything which is earthly, or corporeal, or under the influence of the external senses. On which account it is said to be "like the hoar-frost on the Earth."[Ex 6:16.] For when the man who beholds God, meditates a flight from the passions, "the waves are frozen," that is to say, the impetuous rush, and the increase, and the haughty pride of the waves are arrested, in order that he who might behold the living God might then pass over the Passion.[Ex 16:15.] (173) Therefore the souls inquire of one another, those, that is, that have clearly felt the influence of the word, but which are not able to say what it is. For very often, when sensible of a sweet taste, we are nevertheless ignorant of the flavour which has caused it, and when we smell sweet scents, we still do not know what they are. And in the same manner also the soul very often, when it is delighted, is yet unable to explain what it is that has delighted it; but it is taught by the hierophant and prophet Moses, who tells it, "This is the bread, the food which God has given for the Soul,"[Ex 16:15.] explaining that God has brought it, his own word and his own reason; for this bread which he has given us to eat is this word of his.
