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.

4452. 'And the land shall be before you; dwell' means the Church which would be one. This is clear from the meaning of 'the land' as the Church, dealt with in 566, 662, 1066, 1067, 1413, 1607, 3355, 4447, and from the meaning of 'dwelling with us' as living together, dealt with immediately above in 4451, thus that the Church would be one.
