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.

6231. 'And he said to me, Behold, I am making you fruitful and will cause you to be multiplied' means a bestowal of life through the good of charity and the truth of faith. This is clear from the meaning of 'being made fruitful' as that which has regard to the good of charity, and of 'being multiplied' as that which has regard to the truth of faith, dealt with in 43, 55, 913, 983, 2846, 2847. Since these are what bestow life on a person, the expression 'a bestowal of life through them' is used.
