'Poor' in the Bible

Better is a poor and wise youth than an old and foolish king who doesn't know how to receive admonition any more.

For out of prison he came forth to be king; yes, even in his kingdom he was born poor.

If you see the oppression of the poor, and the violent taking away of justice and righteousness in a district, don't marvel at the matter: for one official is eyed by a higher one; and there are officials over them.

For what advantage has the wise more than the fool? What has the poor man, that knows how to walk before the living?

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.

Then I said, "Wisdom is better than strength." Nevertheless the poor man's wisdom is despised, and his words are not heard.
