'Wall' in the Bible

“So I will send a fire [of war, conquest, and destruction] on the wall of GazaAnd it shall consume her citadels.

“So I will send a fire [of war, conquest, and destruction] on the wall of Tyre,And it shall consume her citadels.”

“So I will kindle a fire [of war, conquest, and destruction] on the wall of Rabbah [in Ammon]And it shall devour its strongholdsAmid war cries and shouts of alarm on the day of battle,And a tempest on the day of the whirlwind [when the enemy captures the city].

“And you shall go out through the breaches [made in the city wall],Every woman straight before her [unable to turn aside],And you shall be cast to Harmon,”Says the Lord.

It is as if a man runs from a lion [escaping one danger]And a bear meets him [so he dies anyway],Or goes home, and leans with his hand against the wallAnd a snake bites him.

Thus He showed me [a vision], and behold, the Lord was standing by a vertical wall with a plumb line in His hand [to determine if the wall was straight or if it needed to be destroyed].
