Arcana Coelestia # 10491
10491. 'And the sons of Levi did according to the word of Moses' means put into effect by those in possession of truths springing from good. This is clear from the representation of 'the sons of Levi' as those in possession of truths springing from good, and in the abstract sense, without reference to persons, as truths springing from good, dealt with above in 10485; and from the meaning of 'doing according to the word of Moses' as putting into effect.
Etham
In Exodus 13:20, Etham signifies the second spiritual state of people who are liberated by the Lord. (Arcana Coelestia 8103)
