'A plain' signifies the extremes of the Word regarding doctrine, and also the extremes of the church, or people in extremes of truths and goods. It also signifies good and truth in the natural self, because 'the people who dwell in plains,' or 'beneath mountains and hills' are in the extreme heaven. In Genesis 19:17, this signifies all doctrinal matters.

In Genesis 11:2, this signifies that their worship became more impure and profane. (Arcana Coelestia 1292)

In Jeremiah 21:13, this signifies the faith in which is no charity. (Arcana Coelestia 4715) Plain and valley signifies the ultimates of the Word. (Apocalypse Explained 411) Plain signifies good and truth in the natural man, because people in the First Heaven dwell in plain or valley. (Apocalypse Explained 449)

1293. 'And they dwelt there' means the life that resulted. This becomes clear from the meaning in the Word of 'dwelling' as living. The expression to dwell occurs many times in both the prophetical and the historical sections of the Word, and in the internal sense it as a rule means to live. The reason is that the most ancient people dwelt in tents and celebrated their most holy worship in them, and this also is why 'tents' in the Word means the holiness of worship, as shown in 414. And since 'tents' meant the holiness within worship, 'dwelling' in a good sense also means living, or life. In a similar way it is because the most ancient people travelled around with their tents that 'travelling' in the internal sense of the Word means the established patterns and order of life.
