In Zechariah 8:12, 'the vine shall give her fruit, and the ground her increase,' signifies that the spiritual affection of truth produces the good of charity, and the natural affection of good and truth produces the works of charity.

(Odkazy: Apocalypse Explained 695)

8987. 'I will not go out free' means the delight of obedience. This is clear from the meaning of 'going out free' as a state after conflict, which is solely one of strengthened and implanted truth, dealt with above in 8976, 8980, 8984. For servitude which lasted for six years and is called 'a week', Genesis 29:27-28, means labour or some conflict such as that undergone by those who are imbued with truths and not with complementary good, that is, those who are meant in the spiritual sense by 'Hebrew slaves'. The character of these people is such that they are not able to be regenerated, only to be reformed. The expression to be regenerated is used in reference to those who allow the Lord to lead them by means of truths, called the truths of faith, to the good of spiritual life; but to be reformed is used in reference to those who cannot be led by means of the truths of faith to the good of spiritual life, only to the delight of natural life.

[2] Those who allow themselves to be regenerated act from affection when they act in accordance with the commandments of faith; but those who do not allow themselves to be regenerated, only to be reformed, act not from affection but from obedience. The difference is that those who act from affection do so from the heart, which means that they act in freedom, and also that they do what is true for its own sake, and what is good for its own sake, and in so doing exercise charity for their neighbour's sake. But those who act from obedience do not act in that way from the heart, or therefore in freedom. If it seems to them that their actions do spring from the heart and are done in freedom, this is due to something of personal glory causing them to feel that way about their actions. Nor do they do what is true for its own sake or good for its own sake, but for the sake of the delight resulting from that glory. Thus they do not exercise charity towards the neighbour for the neighbour's sake, but in order that they themselves may be seen and receive reward. From all this it is clear who exactly they are, and what they are like, who were represented by 'the children of Israel', and who exactly they are, and what they are like, who ho were represented by 'Hebrew slaves'.

[3] But within the Church at the present day recognition of the difference between them has been lost. The reason for this is that faith, not charity, is declared to be and spoken of as the be-all of the Church at the present day. Yet few know what faith is. Most people think that faith consists in knowing the things taught by the Church and in firmly believing that they are true, but not in leading a life in keeping with them. A life in keeping with them is called by them the moral life, which they set apart from the teachings of the Church and term Moral Theology. The learned however think that faith is the confidence or assurance that they are saved through the Lord's having suffered for them and redeemed them from hell. And they say that those possessing this confidence are saved, thus by faith alone. But they do not take into account the truth that the confidence belonging to faith cannot exist except with those who lead a charitable life.

[4] These are the reasons for the loss of the recognition of the difference between those imbued with the truths of faith and not with complementary goodness of life and those who are imbued with goodness of life complementing truths of faith. And since that recognition has been lost the things that are being said about those imbued with truths and not with good, who are meant by 'Hebrew slaves', inevitably appear to be far-fetched.
