Arcana Coelestia # 2917
2917. 'I will bury my dead from before me' means that He would emerge and rise up out of the night prevailing among them. This is clear from the meaning of 'burying' as rising again, dealt with immediately above in 2916, and from the meaning of 'one who is dead' as a state when shadow or night, which is the lack of knowledge, has fallen, also dealt with above in 2908, 2912, from which the Lord emerges and rises again with man when He is acknowledged. Previously He is enveloped in night because He does not appear. He rises again with every person who is being regenerated.
Isaiah 14:20
20
Thou shalt not be joined with them in burial, because thou hast destroyed thy land, and slain thy people: the seed of evil-doers shall never be renowned.
