Arcana Coelestia # 8075
8075. 'And all offspring opening it among the beasts' means all charity belonging to the new birth. This is clear from the meaning of 'whatever opens the womb' as faith springing from charity, which belongs to the new birth, dealt with in 8043; and from the meaning of offspring of the beasts' as the affection for good, dealt with in 45, 46, 142, 143, 246, 714, 715, 719, 776, 1823, 2179, 2180, 3218, 3519, 5198, thus the good of charity.
Arcana Coelestia # 45
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.
