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.
Arcana Coelestia #1451
1451. 'Being removed to the mountain on the east of Bethel means an advance made in the celestial things of love. This becomes clear from the meaning of 'a mountain' as that which is celestial, as shown in 795, 796; from the meaning of 'the east' as Jehovah Himself as regards love, who is the east itself, as has also been shown in 101 and elsewhere; and also from the meaning of 'Bethel' as knowledge of celestial things. Celestial things are implanted both independently of cognitions and together with cognitions. The implantation independently of cognitions occurs during infancy to childhood, as stated just above, whereas the implantation of them together with cognitions occurs after that, from childhood into adult life. And since the Lord was to advance into cognitions of celestial things, which are meant by 'Bethel', it is said here that 'he removed from there to the mountain on the east of Bethel'.
