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.

3766. 'In the field' means provided for the Churches. This is clear from the meaning of 'the field' as the Church as regards good, dealt with in 2971. In the Word the Church is meant by the expressions 'land', 'ground', and 'the field', though each has a different shade of meaning. The reason 'the field' means the Church is that like a field it receives the seeds of goodness and truth; for the Church has the Word, the source of those seeds. This also is why everything included in the field means some aspect of the Church, such as that which is sown, that which is harvested, standing grain, wheat, barley, and everything else. And each of these too has a different shade of meaning.
