'Gates' in the Bible

It had a massive and high wall, with twelve [large] gates, and at the gates [were stationed] twelve angels; and on the gates the names of the twelve tribes of the sons of Israel were written.

On the east side [there were] three gates, on the north three gates, on the south three gates, and on the west three gates.

The one who was speaking with me had a gold measuring rod to measure the city, and its gates and its wall.

And the twelve gates were twelve pearls; each separate gate was of one single pearl. And the street (broad way) of the city was pure gold, like transparent crystal.

By day (for there will be no night there) its gates will never be closed [in fear of evil];

Blessed (happy, prosperous, to be admired) are those who wash their robes [in the blood of Christ by believing and trusting in Him—the righteous who do His commandments], so that they may have the right to the tree of life, and may enter by the gates into the city.
