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.
Arcana Coelestia # 2912
2912. 'Abraham rose up' means a raising up. This is clear from the meaning of 'rising up' as implying some kind of raising up, dealt with in 2401, 2785, here a raising up from grief, for a new Church was about to be established in place of the previous one that perished.
[2912a] 'From before his dead' means in that [state of] night. This is clear from the meaning of 'dying', 'death', and 'one who has died' as night as regards the state of the Church, dealt with above in 2908.
