All changes of place in the Bible represent changes in spiritual state. “Entering” – usually used as entering someone’s house or “going in unto” someone – particularly means adopting a spiritual state that is compatible with someone else in order to communicate with them or be conjoined with them. This is easily seen in the fact that a man “going in unto” a woman is sort of a Biblical euphemism for a physical relationship. In a broader sense, all the spiritual changes we go through in our lives involve “entering” and “leaving,” so when the Bible uses the phrasing “going in and coming out,” it symbolizes someone’s entire spiritual life.

To enter, as in Genesis 7:1, signifies to be prepared.

In Leviticus 22:6, this signifies a state of being in falsities. (Arcana Coelestia 1666)

In Hosea 9:3, this signifies appropriating things impure and profane derived from reasoning. (Arcana Coelestia 4581[10], Apocalypse Explained 654[56]) 'Pollution' denotes the truth of faith defiled.
