45. This was how people who lived in most ancient times envisaged matters of the understanding and those of the will. Among the Prophets therefore, and consistently throughout the Old Testament Word, like matters are represented by various kinds of living creatures. There are two kinds of beasts - evil ones, because they are harmful, and good ones, because they are gentle. Evil [and harmful] things in man were meant by such beasts as bears, wolves, and dogs, while good and gentle things were meant by beasts such as calves, sheep, and lambs. As the subject here is those persons who are to be regenerated, 'the beasts' are good and gentle ones, which mean affections. Things of a baser nature that derive from the body are called 'wild animals of the earth'. These are desires and pleasures.

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.
