3593. 'And Isaac trembled very greatly' means the great change that accompanied the inversion of state. This is clear from the meaning of 'trembling' as a change that took place. Its accompanying the inversion of state is evident from what has been stated above about the two states a person passes through when being regenerated - the state before he has been regenerated and the state after. That is to say, in the state before he has been regenerated truths apparently have dominion, but in the state after he has been regenerated, truths give way and good acquires dominion - see what has often been shown already, in 1904, 2063, 2189, 2697, 2979, 3286, 3288, 3310 (end), 3325, 3330, 3332, 3336, 3470, 3509, 3539, 3548, 3556, 3563, 3570, 3576, 3579.

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.
