That this signifies the effect of the power of internal truth through external truth against falsities, is evident from the representation of Aaron, as being the doctrine of truth and good, thus external truth (see n. 6998, 7009, 7089); from the signification of "hand," as being power (n. 878, 4931-4937), here the power of internal truth through external (as above, n. 7382); and from the signification of "the waters of Egypt," as being falsities (n. 6693, 7307). The effect is signified by "stretching out the hand and the frogs coming up." From all this it is evident that by "Aaron stretched out his hand over the waters of Egypt," is signified the effect of the power of internal truth through external truth against falsities.
