'Poor' in the Bible

Only it was their desire that we would give thought to the poor; which very thing I had much in mind to do.

But now that you have come to have knowledge of God, or more truly, God has knowledge of you, how is it that you go back again to the poor and feeble first things, desiring to be servants to them again?

And you did not have a poor opinion of me because of the trouble in my flesh, or put shame on it; but you took me to your hearts as an angel of God, even as Christ Jesus.
