'Gates' in the Bible

And her gates will lament and mourn,And deserted she will sit on the ground.

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

I said, “In the middle of my lifeI am to enter the gates of Sheol;I am to be deprived of the rest of my years.”

Thus says the Lord to Cyrus His anointed,Whom I have taken by the right hand,To subdue nations before himAnd to loose the loins of kings;To open doors before him so that gates will not be shut:

“Moreover, I will make your battlements of rubies,And your gates of crystal,And your entire wall of precious stones.

“Your gates will be open continually;They will not be closed day or night,So that men 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.

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