7269. Also Aaron thy brother shall be thy prophet. That this signifies the doctrine thence derived, is evident from the signification of a “prophet,” as being the truth of doctrine, thus doctrine from the Word (see n. 2534). (That Aaron represents the doctrine of the church, or the doctrine of good and truth which is from the Word, see n. 6998, 7009, 7089.) As a “prophet” signifies doctrine, in a determinate sense it signifies one who teaches, according to what was said just above (see n. 7268 at the end).
Arcana Coelestia #8001
8001. 'Shall eat it' means that he shall be together with them. This is clear from the meaning of 'eating' - eating the Passover lamb together with all the others - as communicating, and being joined together, dealt with in 2187, 5643. For the Passover supper represented, as stated above in 7836, 7891, 7996, 7997, groups of angels associated together according to forms of good and truths; and the statutes regarding foreigners, slaves, strangers, hired servants, and sojourners, who are dealt with in these verses, in the internal sense indicate who exactly could be integrated among them and who could not. This then is why 'eating' means being together with them or integrated among them, while 'not eating' means not being together among them, that is, being set apart from them.
