Arcana Coelestia # 7638
7638. 'And said to him' means discernment. This is clear from the meaning of 'saying' as discerning, dealt with in 1791, 1815, 1819, 1822, 1898, 1919, 2080, 2619, 2862, 3395, 3509, 5743, 5877. The reason why 'said' here means discerning is that by 'Moses and Aaron' God's truth is represented, 'going to' means its presence, and the presence of God's truth leads to discernment.
Arcana Coelestia # 1822
1822. That 'He said to him' means perception is clear from what has been stated above at verses 2 and 7. Perception itself is nothing else than a certain form of conversing that takes place inwardly, but which makes itself known whenever the spoken word is grasped perceptively. Every form of inward dictate, even conscience, is nothing else; but perception is a higher or more interior degree of it.
