'Gates' in the Bible

It has a massive, high wall with twelve gates, with twelve angels at the gates, and the names of the twelve tribes of the nation of Israel are written on the gates.

There are three gates on the east side, three gates on the north side, three gates on the south side and three gates on the west side.

And the twelve gates are twelve pearls -- each one of the gates is made from just one pearl! The main street of the city is pure gold, like transparent glass.

Its gates will never be closed during the day (and there will be no night there).

Blessed are those who wash their robes so they can have access to the tree of life and can enter into the city by the gates.
