Arcana Coelestia # 6455
6455. 'In the cave which is in the field of Machpelah' means in that obscurity. This is clear from the meaning of 'the cave', and also of 'Machpelah', as obscurity. For the meaning of 'the cave' as obscurity, see 2975, 6453, and of 'Machpelah', 2935, though 'Machpelah' means the essential nature of the obscurity.
Arcana Coelestia # 6453
6453. 'At the cave' means where obscurity exists. This is clear from the meaning of 'the cave' as obscurity, dealt with in 2935. Regarding the existence of obscurity as well in the exterior natural, where the truths and forms of good represented by 'the sons and tribes of Israel' are, because things exist there only as a general, single whole, see just above in 6451 (end).
