Walls and palaces
In Lamentations 2:7 and Psalm 122:7, the walls and palaces signify all protecting truths, both interior and exterior. (Apocalypse Explained 391[15])
North
'North,' in Isaiah 14:31, signifies hell. 'The North,' as in Jeremiah 3:12, signifies people who are ignorant of truth, and yet have the life of good. 'North' signifies people in obscurity regarding truth.
