Arcana Coelestia # 9750
9750. 'And [the same shall be] so for the length on the north side' means where the good of truth dwells in obscurity. This is clear from the meaning of 'the north side' as the place where truth dwells in obscurity, dealt with in 3708; and from the meaning of 'length' as good, dealt with in 1613, 9487.
Jeremiah 1:13-15
13
The word of Yahweh came to me the second time, saying, "What do you see?" I said, "I see a boiling caldron; and it is tipping away from the north."
14
Then Yahweh said to me, "Out of the north evil will break out on all the inhabitants of the land.
15
For, behold, I will call all the families of the kingdoms of the north," says Yahweh; "and they shall come, and they shall each set his throne at the entrance of the gates of Jerusalem, and against all its walls all around, and against all the cities of Judah.
