Arcana Coelestia #2922
2922. 'In the choicest of our graves' means well-pleasing in regard to regeneration. This is clear from the meaning of 'choosing', 'a choice', and 'choicest' as that which is preferred or well-pleasing, and from the meaning of 'a grave' as resurrection and regeneration, dealt with above in 2916.
Ezekiel 13:13
13
Therefore thus says the Lord Yahweh: I will even tear it with a stormy wind in my wrath; and there shall be an overflowing shower in my anger, and great hailstones in wrath to consume it.
