'Gates' in the Bible

The ways of Zion do mourn, because none come to the solemn assembly; All her gates are desolate, her priests do sigh: Her virgins are afflicted, and she herself is in bitterness.

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

The kings of the earth believed not, neither all the inhabitants of the world, That the adversary and the enemy would enter into the gates of Jerusalem.
