6637. 'These are the names of the children of Israel' means the essential nature of the Church. This is clear from the meaning of' the name as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2628, 2724, 3006, 3421; from the representation of 'the sons of Israel' as spiritual truths, dealt with in 5414, 5879, 5951; and from the representation of 'Israel' as the good of truth, which is spiritual good, dealt with in 3654, 4598, 5803, 5806, 5812, 5817, 5819, 5826, 5833. Since Israel' represents the good of truth or spiritual good and 'his sons' represent spiritual truths in the natural, 'the sons of Israel' also represent the Church, for what makes it the Church is spiritual good and the truths that spring from that good. A person without spiritual good, that is, the good of charity, and without spiritual truths, that is, the truths of faith, does not belong to the Church in spite of having been born within the Church. The whole of the Lord's heavenly kingdom possesses the good of love and faith, and unless the Church possesses good like that it cannot be the Church since it is not joined to heaven; for the Church is the Lord's kingdom on earth.

[2] The term 'Church' is not used because it is the place where the Word is and teachings drawn from it, or because it is where the Lord is known and the sacraments are celebrated. Rather it is the Church because it lives in accordance with the Word or with teachings drawn from the Word, and seeks to make those teachings its rule of life. People who do not live like this do not belong to the Church but are outside it; and those who lead wicked lives, thus lives contrary to that teaching, are further away outside the Church than gentiles who know nothing whatever about the Word, the Lord, or the sacraments. For since those people are acquainted with the forms of good that the Church fosters and with the truths it teaches they annihilate the Church within themselves, something gentiles cannot do because they are unacquainted with those things. It should also be realized that everyone who leads a good life, in charity and faith, is a Church, and is a kingdom of the Lord. He is for that reason also called a temple, and a house of God too. Those who are Churches individually, no matter how remote from one another they may be, constitute one Church collectively. This then is the Church meant by the expression 'the children of Israel' here and in what follows.

6647. 'And the children of Israel were fruitful and productive' means that the Church's truths increased in goodness. This is clear from the representation of 'the children of Israel' as spiritual truths, dealt with in 5414, 5879, and as the Church, 6637; from the meaning of 'being fruitful' as increasing in goodness, dealt with in 43, 55, 917, 983, 2846, 2847, 3146; and from the meaning of 'being productive' as further branching out; for once the Church has been established with a person, good increases constantly and branches out both within the internal and also towards the external, and within it. It has often been shown already that among those who belong to the spiritual Church good is increased by means of truths; for a member of the spiritual Church does not have perception as a member of the celestial Church has, and therefore he has no knowledge of what the Church's good - that is, spiritual good - is except through truths. This being so, when a member of that Church is being regenerated, the Lord uses the angels present with that person to bring truths to his awareness, and from those truths he is led on to good. But when that person has been regenerated, He brings both truth and good together to his awareness, and thereby leads him. But the character of the good with a member of the spiritual Church is determined by that of the truth, and so therefore is the character of his conscience, which serves him in place of perception, as a guide to the way he lives.

4598. 'Israel travelled on' means the celestial-spiritual of the natural then. This is clear from the meaning of 'travelling on' as a further stage or a continuation, dealt with in 4375, 4554, in this case towards aspects more interior still, and from the representation of 'Israel' here as the celestial-spiritual of the natural, dealt with in 4286. What the celestial-spiritual of the natural is has been explained already, namely the good of truth, or the good of charity arrived at through the truth of faith. Little knowledge exists in the world of what an advance towards more interior aspects is. It is not an advance into knowledge of facts, for that kind of advance is often made without any advancement towards interior things, and more often still is accompanied by a movement away from these. Neither is it an advance in maturity of judgement, for this too is sometimes accompanied by a movement away from interior things. Nor yet is it an advance made into cognitions of interior truth, for these count for nothing if a person does not have any affection for them. An advance towards interior things is an advance nearer to heaven and the Lord made by means of the cognitions of truth which have been implanted in an affection for them, and so is an advance made by means of the affections.

[2] What an advance towards interior things is like is not apparent to anyone in the world; but in the next life it is plain to see. In that life it is an advance out of a kind of haze into light; for compared with others people who are concerned solely with more external things live in a haze, and are also seen by the angels to do so, whereas those who have a concern for more internal things dwell in light, and consequently in wisdom since the light there is wisdom. And what is amazing, those living in the haze cannot see that those in light are in light, whereas those dwelling in light can see that those in the haze are in a haze. Since the subject is the advance made by the Lord's Divine towards more interior aspects, Jacob is called Israel here; but where that advance is not the subject he is called Jacob, as in verse 20 immediately before this, and in the final verse of this chapter.
