'Gates' in the Bible

And Jerusalem’s gates will lament (cry out in grief) and mourn [as those who wail for the dead];And she, being ruined and desolate, will sit upon the ground.

Lift up a signal banner on the bare mountain,Summon them [the Medes and Persians] with a loud voice,Wave the [beckoning] hand so that they may enter the doorways of the [Babylonian] nobles.

They set the table [for the doomed banquet], they spread out the cloth, they eat, they drink;“Rise up, captains [of Belshazzar’s court], oil your shields [for battle, for your enemy is at the gates]!”

“Open the gates, that the righteous nation may enter,The one that remains faithful and trustworthy.

I said, “In mid-lifeI am to go through the gates of Sheol (the place of the dead),I am to be summoned, deprived of the remainder of my years.”

This is what the Lord says to His anointed, to Cyrus [king of Persia],Whose right hand I have heldTo subdue nations before him,And I will ungird the loins of kings [disarming them];To open doors before him so that gates will not be shut:

“And I will make your battlements of rubies,And your gates of [shining] beryl stones,And all your [barrier] walls of precious stones.

“Your gates will be open continually;They shall not be shut day or night,So that people may bring to you the wealth of the nations—With their kings led in procession.

“Violence will not be heard again in your land,Nor devastation or destruction within your borders;But you will call your walls Salvation, and your gates Praise [to God].

Go through, go through the gates,Clear the way for the people;Build up, build up the highway,Remove the stones, lift up a banner over the peoples.
