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.
Luke 2:11
11
For there is born to you, this day, in the city of David, a Savior, who is Christ the Lord.
