Arcana Coelestia#8012
8012. 'And no uncircumcised person shall eat it' means that no one ruled by self-love and love of the world may be together with them. This is clear from the meaning of one who is 'uncircumcised' as one who is ruled by self-love and love of the world, dealt with in 2056, 3412, 3413, 7045; and from the meaning of 'eating it' - eating the Passover - as being together with them, dealt with above in 8001.
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.
