Arcana Coelestia #9403
9403. 'And Moses and Aaron went up, Nadab and Abihu' means the Word in its inward and outward senses, and teachings derived from both senses. This is clear from the representation of 'Moses and Aaron' as the Word in its inward and outward senses; and from the representation of 'Nadab and Abihu', Aaron's sons, as teachings derived from both senses, all of whom are dealt with above in 9374, 9375.
Arcana Coelestia #9374
9374. 'You and Aaron' means the Word in its inward and outward senses. This is clear from the representation of 'Moses' as the Word, dealt with above in 9373; but when Aaron, who was his brother, is linked with him, 'Moses' represents the Word in its inward sense, and 'Aaron' the Word in its outward sense, as also before in 7089, 7382.
