7999. 'A purchase paid for with silver' means who is in possession of some spiritual truth. This is clear from the meaning of 'a purchase' as that which is acquired and made one's own, dealt with in 4397, 4487, 5374, 5397, 5406, 5410, 5426; and from the meaning of 'silver' as truth, dealt with in 1551, 2954, 5658, at this point spiritual truth since a slave who was bought means in the internal sense the natural man, and the master who bought him therefore means the spiritual man. No one can know what this really implies unless he knows in what way the spiritual buys the natural for itself, that is, acquires and makes it its own. When a person is being regenerated his internal and external, that is, his spiritual and natural, are at variance with each other at first; for his spiritual desires the things of heaven, whereas his natural desires those of the world. But at this time the spiritual is constantly entering the natural and bringing it into agreement. This is done by means of truth; and what the spiritual brings into agreement with itself within the natural is said to be 'bought with silver', that is, acquired and made its own by means of truth.

4397. 'And he bought the portion of the field' means making the good that springs from that truth its own. This is clear from the meaning of 'buying' as making one's own, and from the meaning of 'the portion of the field' as good springing from that truth. For 'the field' means the Church as regards good and so means good itself, see 2971, 3196, 3317, 3500, 3508, 3766.
