1 Samuel 25:33

³³ And blessed be thy advice, and blessed be thou, which hast kept me this day from coming to shed blood, and from avenging myself with mine own hand.

Wall, rampart, gates, and bars

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

⁹ Her gates are sunk into the ground; he has destroyed and broken her bars: Her king and her princes are among the nations where the law is not; Yes, her prophets find no vision from Yahweh.
