'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)

6439. Verse 27 Benjamin is a wolf; he will seize in the morning, he will devour the spoil, and at evening he will divide the plunder. 'Benjamin' means the truth of good present in the spiritual Church, which is 'Joseph'. 'Is a wolf' means an eagerness to rescue and deliver the good. 'He will seize in the morning, he will devour the spoil' means that the deliverance takes place when the Lord is present. 'And at evening he will divide the plunder' means their possession in the Lord's kingdom, while they are still in obscurity.
