That this signifies power against the falsities of those who infest, is evident from the signification of a "rod," as being natural power, and from the signification of the "hand," as being spiritual power (of which above, n. 7309), hence "to take a rod and stretch out the hand" denotes to exercise spiritual power by means of natural power; and from the signification of "the waters of Egypt," as being the falsities which infest (of which also above, n. 7307).
