Arcana Coelestia #4507
4507. 'And whatever was in the city, and whatever was in the field they took' means every truth and good of the Church. This is clear from the meaning of 'the city' as doctrine, and so the truth of the Church, dealt with in 402, 2268, 2449, 2712, 2943, 3216, 4492, 4493, and from the meaning of 'the field' as the Church in regard to good, and so as the good of the Church, dealt with in 2971, 3310, 3766, 4440, 4443. Consequently 'whatever was in the city, and whatever was in the field' means every truth and good of the Church.
Arcana Coelestia #2971
2971. 'The field and the cave which was in it' means as regards the good and truth of faith. This is clear from the meaning of 'the field' as the Church and also good itself which constitutes the Church (that which is celestial - or good that stems from love to the Lord and charity towards the neighbour - is compared to 'the ground' as well as to the field, and is actually called these, because that which is celestial - or good - is the recipient of the truths of faith; and these truths are compared to and are also actually called 'seeds'); and from the meaning of 'a cave' as the truth of faith which is enveloped in obscurity, dealt with in 2935. It is said to be in obscurity because it is with spiritual people, see 1043, 2708, 2715.
