'Walls' in the Bible

The Lord rejected his altar, disavowing his sanctuary. He gave up her palace walls to the control of the enemy. They shouted in the LORD's Temple, as though they were attending a day of celebration.

The LORD planned to destroy the walls of cherished Zion. He measured them with his line. He did not withhold his hand from destruction. He made both ramparts and defensive walls mourn; they languish together.
