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 Matthew 24:32, the branch signifies affection, for affection springs and flourishes from good as a branch springs from its trunk.

In Malachi 4:1, the branch denotes truth.

In Isaiah 19:15, a branch signifies spiritual truth, and bulrushes things that are sensual and worldly.

In Exodus 25:33, this signifies the power of truth from good—for a branch is like the arms of a man. (Arcana Coelestia 9555, 9558)
