7385. 'And Aaron stretched out his hand over the waters of Egypt' means the effect of the power of inward truth directed through outward truth against falsities. This is clear from the representation of 'Aaron' as teachings presenting what is true and good, thus outward truth, dealt with in 6998, 7009, 7089; from the meaning of 'hand' as power, dealt with in 878, 4931-4937, at this point the power of inward truth directed through outward truth, as above in 7382; and from the meaning of 'the waters of Egypt' as falsities, dealt with in 6693, 7307, the effect being meant by the fact that he did stretch out his hand and the frogs rose up. From all this it is evident that 'Aaron stretched out his hand over the waters of Egypt' means the effect of the power of inward truth directed through outward truth against falsities.

7009. 'And it will happen, that he will be for you as a mouth' means the truth contained in doctrinal teachings, which also goes forth from the Lord in an indirect way. This is clear from the representation of Aaron, who 'will be for Moses as a mouth', as doctrinal teachings, dealt with in 6998; and from the meaning of 'being for Moses as a mouth' as the utterance or declaration of it, dealt with in 6987. The reason why the words of explanation are 'the truth contained in doctrinal teachings, which also goes forth from the Lord in an indirect way' is that the truth contained in doctrinal teachings, which 'Aaron' represents, is the kind of truth that can be heard and discerned by angels and by men. Such truth is what goes forth in an indirect way from the Lord. But the kind of truth that is represented by 'Moses' goes forth directly from the Lord, and cannot be heard or discerned by men, nor even by angels, see 6982, 6985, 6996, 7004.
