7424. 'And there were lice on man and on beast' means that evils rose up from those things - interior and exterior evils attached to wicked desires. This is clear from the meaning of 'lice' as evils, dealt with in 7419; from the meaning of 'man' as good, dealt with in 4287, 5302, and so in the contrary sense as evil; and from the meaning of 'beast' as the affection for good, and in the contrary sense as the affection for evil, which is evil or wicked desire, dealt with in 45, 46, 142, 143, 246, 714, 715, 719, 776, 2179, 2180, 3218, 3519, 5198. But when the expression 'man and beast' is used, man' means interior good, and in the contrary sense interior evil, while 'beast' means exterior good, and in the contrary sense exterior evil. The reason why 'man' means interior good or interior evil is that a person is truly human by virtue of his internal man and the nature of this, not by virtue of his external man; for without the internal the external man is not truly human. If the external man too is to be truly human it must be completely subject to the internal, so completely that it does not act by itself, only from the internal. The reason why 'beast' means exterior good and in the contrary sense exterior evil is that beasts do not have an internal side to them like that present in a human being. With them the internal side is merged into the external, so completely that it makes one with it, and at the same looks downwards or towards the ground without any uplifting towards more internal things. The expression 'evils attached to wicked desires' is used because all evils are objects of wicked desires; for wicked desires are the longings of a person's loves. What makes interior evils different from exterior evils is this: Interior evils belong to thought and will, whereas exterior evils belong to actions. The fact that evils may be interior without being exterior is evident from the consideration that a person can be evil and yet to outward appearance look like an upright man, indeed like a man possessing faith and conscience. Some even know how to pretend to be angels when in fact inwardly they are devils. This is how great the difference can be between the inward appearance, which is that presented by the spirit, and the outward appearance, which is that presented by the body.

719. 'The beast that is not clean' means evil affections. This is clear from what has been stated and shown already about clean beasts. The clean ones are so called because they are gentle, good, and useful. Those that are not clean are the opposite - savage, evil, and useless - of which there are genera and species. These in the Word are also portrayed as wolves, bears, foxes, pigs, and many others, which mean various evil desires and malicious intentions. In the present verse it is said that unclean beasts, or evil affections, were to be taken into the ark as well, for the following reason: The character of the member of this Church is being described here, specifically by means of the ark, and thus by the things that were in or rather had been brought into the ark, that is, the things that already resided with man prior to his being regenerated. Truths and goods resided with him already, which the Lord had supplied and granted prior to his regeneration, for without truths and goods no one can possibly be regenerated. Here the evils that resided with him are referred to and are meant by 'unclean beasts' that are mentioned. While a person is being regenerated evils are present that have to be dispersed, that is, broken down and modified by means of goods. For no evil with man, that of his own doing or that which is hereditary, can ever be dispersed so far as to be banished, but remains implanted for ever. Yet it is broken down and modified by means of goods from the Lord so as to be innocuous and not seen. This is an arcanum that is still unknown. It is the evils of man's own doing that are broken down and modified, rather than those which are hereditary - something else which is not known.
