'Poor' in the Bible

Better is a poor and wise youth than an old and foolish king, who knoweth not how to receive admonition any more.

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

If thou seest the oppression of the poor, and the violent taking away of justice and righteousness in a province, marvel not at the matter: for one higher than the high regardeth; and there are higher than they.

For what advantage hath the wise more than the fool? or what hath the poor man, that knoweth how to walk before the living?

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

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