Cisterns
In Genesis 26, the well signifies that people who were in the mere worldly knowledge of truths of faith were unwilling to make the internal nature of the Divine more well-known. (Arcana Coelestia 3412)
Broken cisterns in Jeremiah 2:13 signify false doctrines.
In Deuteronomy 6:11, cisterns hewn out signify the interiors of the natural mind–full of knowledge of good and truth. (Apocalypse Explained 617[13])
