'City' in the Bible

Wisdom gives more strength to the wise than ten rulers who are in the city.

Meanwhile, I saw the wicked being [honorably] buried, but those who came and went from the holy place were forgotten in the city, even though they had done so. This also [is] vanity!

[There was] a small city with few people in it. A great king came and besieged it, building great siege works against it.

Now, a poor wise man was found in it, and he delivered the city by his wisdom.
