Arcana Coelestia # 1665
1665. Verse 3 All these were gathered together at the valley of Siddim, which is the Salt Sea.
'All these were gathered together at the valley of Siddim' means that they were immersed in the unclean things that go with evil desires. 'Which is the Salt Sea' means the foul things that accompany derivative falsities.
Jeremiah 6:3-5
3
Shepherds with their flocks shall come to her; they shall pitch their tents against her all around; they shall feed everyone in his place."
4
"Prepare war against her; arise, and let us go up at noon. Woe to us! For the day declines, for the shadows of the evening are stretched out.
5
Arise, and let us go up by night, and let us destroy her palaces."
