6550. 'As a possession for a grave, from Ephron the Hittite' means those who receive the truth and good of faith and allow themselves to be regenerated. This is clear from the meaning of 'a grave' as regeneration, dealt with in 2916, 2917, 5551, 6459; and from the representation of 'Ephron the Hittite' as those with whom the ability exists to receive goodness and truth, dealt with in 6458.

4613. 'To Mamre, Kiriath Arba' means its state. This is clear from the meaning of 'Mamre' as the nature and extent of that to which it is allied, dealt with in 2970, and from the meaning of 'Kiriath Arba' as the Church as regards truth, dealt with in 2909, and so means truth. Hence 'Mamre, Kiriath Arba' means the state of the natural as regards truth, and 'Hebron' its state as regards good, dealt with immediately below.
