Arcana Coelestia # 9953
9953. 'And his sons with him' means such a state there in the outward things emanating from that [Divine Good]. This is clear from the meaning of 'to clothe' as to bring about a state such as is represented by garments, dealt with immediately above in 9952, at this point that which is represented by the garments of Aaron's sons, which is the state in the spiritual kingdom of the outward things emanating from Divine Truth. For that which emanates is meant by 'sons', and so too by their 'garments', as accords with what has been stated just above in 9950.
Exodus 40:13-15
13
You shall put on Aaron the holy garments; and you shall anoint him, and sanctify him, that he may minister to me in the priest's office.
14
You shall bring his sons, and put coats on them.
15
You shall anoint them, as you anointed their father, that they may minister to me in the priest's office. Their anointing shall be to them for an everlasting priesthood throughout their generations."
