'Gates' in the Bible

The ways of Zion are mourning, Without any coming at the appointed time, All her gates are desolate, her priests sigh, Her virgins are afflicted -- and she hath bitterness.

Sunk into the earth have her gates, He hath destroyed and broken her bars, Her king and her princes are among the nations, There is no law, also her prophets Have not found vision from Jehovah.

Believe not did the kings of earth, And any of the inhabitants of the world, That come would an adversary and enemy Into the gates of Jerusalem.
