8529. 'And Moses said to Aaron' means influx. This is clear from the meaning of 'saying' - when the path is from inward Divine Truth, represented by 'Moses', to outward God's truth, represented by 'Aaron' - as influx. For the path along which Divine influx passes lies through the truth that goes forth directly from the Lord, and on into the truth that goes forth in an indirect way. The fact that in the representative sense 'Moses' and 'Aaron' are those kinds of truth, see 7009, 7010, 7382.

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.
