Amos 5:3

³ For thus saith the Lord GOD; The city that went out by a thousand shall leave an hundred, and that which went forth by an hundred shall leave ten, to the house of Israel.

Wall, rampart, gates, and bars

In Lamentations 2:8-9, the 'wall,' 'rampart,' 'gates,' and 'bars' signify doctrines.

⁸ Yahweh has purposed to destroy the wall of the daughter of Zion; He has stretched out the line, he has not withdrawn his hand from destroying; He has made the rampart and wall to lament; they languish together.
