10237. 'For washing' means purification from evils and falsities. This is clear from the meaning of 'washing' as purification from evils and falsities, dealt with in 3147, 5954. Since purification from evils and falsities by means of the truths of faith is the subject in the internal sense of the verses that now follow, what the situation is with purification must be stated briefly. By 'washing' purification is meant, by 'water' the truths of faith are meant, and by 'the laver' containing the water the natural is meant; for all spiritual purification is accomplished within the natural. A person possesses an external and an internal; the external is called the natural and also the natural man, while the internal is called the spiritual and also the spiritual man. They are so called because the person's internal exists in the spiritual world, where spirits and angels are, while his external exists in the natural world, where people are. Both of them, the internal and the external, undergo purification; the internal does so in heaven, and the external in the world while the person is living there, thus within the natural which exists in the world.

[2] The reason why purification takes place within the natural at this time is that the truths of faith within the natural are clearly perceptible; for they exist there among known facts or things in the memory which are perceived clearly when they are brought to mind. It is different however with things that are thought about in the internal man. These do not come to be seen plainly while a person is in the world, because the ideas there are spiritual. This explains why purification is accomplished within the natural. The fact that it is accomplished by means of the truths of faith becomes clear from the consideration that those undergoing purification should not merely know what evil and falsity are but also acknowledge them to be such, and then turn away and flee from them. When this is done the person starts to be purified from them. Evils and falsities cannot be so known or acknowledged except within the natural through the truths of faith, for these teach what they are and so make them plain. The person who believes that he is purified from evils and falsities before seeing and acknowledging those present in himself is very much mistaken, see 8388, 8390ff.

[3] The reason for saying that a person may know his own evils and falsities through the truths of faith within the natural, that is, in the external man, but not in the internal, is that the ideas belonging to thought in the internal man are spiritual, and spiritual ideas cannot be grasped within the natural. This is because they are ideas in the understanding which are unconnected with objects such as exist in the material world. Nevertheless these ideas, that is to say, spiritual ones, which belong properly to the internal man, flow into natural ideas, which belong to the external man; they produce and fashion those natural ideas, doing so by means of correspondences. But more about spiritual ideas belonging to the internal man will in the Lord's Divine mercy be told in a description of heaven and of spirits and angels; ¹ for they use spiritual ideas for thinking and also for talking to one another.

10237a. 'And you shall put it between the tent of meeting and the altar' means in order that truth and good may be joined together. This is clear from the meaning of 'between the tent of meeting and the altar' as the joining together of truth and good, dealt with in 10001, 10025. The reason why the laver was to be placed between the tent of meeting and the altar, and why Aaron and his sons were to wash their hands and feet there, was in order that purification of the heart and regeneration, which essentially is the joining together of truth and good, might be represented. For truth and good joined together constitute heaven itself with a person. This also is why heaven is compared in the Word to a marriage. That joining together is accomplished by means of the truths of faith, because these teach people the way to lead their life; and therefore when they lead a life in accord with the truths of faith a joining together of truth and good is accomplished. For then truth is transformed into good through the life they lead. The life of truth is goodness. The same thing is meant by the reference to a person's being regenerated by 'water and the spirit', 'water' being the truth of faith, and 'the spirit' its life.

Regeneration is the joining together of truth and good, see 2063, 3155, 3158, 3607, 4353, 5365, 5376, 8516, 8517, 8772, 10067.

6690. 'That He made them houses' means that it - true factual knowledge in the natural - was arranged into a heavenly pattern. This is clear from the meaning of 'house' as the natural mind, dealt with in 4973, 5023, thus the things that compose the natural mind. But because what is said here refers to the midwives, those things are true factual knowledge in the natural, 6687. 'Making them houses' therefore means arranging that knowledge into order, and it is arranged into order when arranged into a heavenly pattern. It is not at all easy to see that these things are meant by 'making them houses' unless one knows the situation with true factual knowledge that belongs to the natural mind. Something must therefore be said briefly about this. Known facts in the natural are arranged into continuous series, one series tying in with another, so that they all hang together according to the varying relationships and close associations they have with one another. They are not unlike families and their generations; for one is born from another, and in that manner they are brought into existence. This explains why things of the mind, which are forms of good and truth, were spoken of by the ancients as 'houses', the form of good that ruled there being called the father, the truth linked to it the mother, and the derivations from them the sons, daughters, sons-in-law, daughters-in-law, and so on. But the way in which true factual knowledge in the natural is arranged varies from person to person, since the pattern it assumes is imposed on it by the ruling love. That love is at the centre and arranges each fact into position around it. It positions nearest to itself the facts most compatible with it, and the rest are arranged according to their degrees of compatibility. And in this way factual knowledge is given a pattern. If heavenly love rules, then the Lord arranges them all into a heavenly pattern, a pattern like that assumed by heaven itself, thus the pattern assumed by the good of love itself. Such is the pattern into which truths are arranged; and once arranged into it they act in unison with good. At this point when the one is stimulated by the Lord, so is the other; that is to say, when items of belief are stimulated, so are charitable desires, and vice versa. This kind of arrangement is what is meant by the statement that God made the midwives houses.
