'City' in the Bible

Wisdom is a strength to the wise man more than ten rulers who are in a city.

So I saw the wicked buried. Indeed they came also from holiness. They went and were forgotten in the city where they did this. This also is vanity.

There was a little city, and few men within it; and a great king came against it, besieged it, and built great bulwarks against it.

Now a poor wise man was found in it, and he by his wisdom delivered the city; yet no man remembered that same poor man.

The labor of fools wearies every one of them; for he doesn't know how to go to the city.
