Arcana Coelestia # 2923
2923. 'Bury your dead' means that in this way they would emerge from night and be raised up into life. This is clear from the meaning of 'burying' as rising again or being raised up to life, dealt with in 2916, and from the meaning of 'one who is dead' as night as regards goods and truths of faith, dealt with in 2908, 2912, 2917.
Ezekiel 32:25-26
25
They have set her a bed in the midst of the slain with all her multitude; her graves are around her; all of them uncircumcised, slain by the sword; for their terror was caused in the land of the living, and they have borne their shame with those who go down to the pit: he is put in the midst of those who are slain.
26
There is Meshech, Tubal, and all their multitude; their graves are around them; all of them uncircumcised, slain by the sword; for they caused their terror in the land of the living.
